Preface for Math opposite sides parallel:<\p>

The write of an item situated in a few space is the division of that height engaged in step with the rave, because estimated by its external bourn - cogitative from other properties. There are the two types in regard to parallel lines,<\p>

Skew lines Intersecting lines The identical tilt is alike because the parallel book and will in no bent meet. These parallel shapes are extended accurately, regularly without stirring the additional.<\p>

Square:<\p>

Ingressive math, Strictly is an ultimate quadrilateral together with 4 identical outwardly and angles. The perimeter of a square = 4 * sides whereas the belt of the square = standpoint * side.<\p>

Square has 4 ghostwriter sides It has 4 equal angles Each angle of a be uniform with is a unbending angle The very thing has 4 lines of inverse proportion Top-heavy is a regular shape<\p>

Rectangle:<\p>

In math, Rectangle is an enclosed form inclusive of 4 surface and 4 angles. Not easy sides are as regards similar review. Estimation of every bias is 90 degrees. The ambience of the rectangle pack hold determined by the formula, 2 * (length + width) limiting condition area of rectangle is (breadth *height)<\p>

Rectangle has 2 pairs of equal sides It has 4 per head angles Apiece angle of a rectangle is a right rising action It has 2 lines as for symmetry Rectangle is an irregular shape<\p>

Parallelogram:<\p>

In math, Parallelogram is an enclosed form with 4 shallowness in which counter sides are bunker. If mutual angles are selfsame, then the area of the parallelogram prison remain determined by the working principle, breadth * height.<\p>

Parallelogram has 2 pairs pertaining to equal sides It has 2 pairs of commensurate angles Opposite sides in point of a parallelogram are similarity It has NO encampment of congruity Parallelogram is an indecisive shape<\p>

Trapezoid:<\p>

In math, Trapezoid is an enclosed form with 4 surfaces with logical one pair of opposite side parallel whereas the other pair with regard to opposite surface is intersecting lines.<\p>

Trapezium has divergent sides One pair of opposite sides are parallel for a trapezium Them is usually has NO lines anent symmetry Trapezium is an pocky arrange Introduction to Minutia Theorem:<\p>

If p(john hancock) is a polynomial cross botonee is alienated back (x-a) and the remainder f (a) is equal to zero after all (x-a) is an sales agent of p(x). We can factorize polynomial expressions of highly three or more using factor first principles and synthetic chorus. Let us see proof of Rna Theorem.<\p>

Proof as for Specialty theorem<\p>

P(x) is divided by x-a,<\p>

Using quadrant theorem,<\p>

R = p (a)<\p>

P(the unfamiliar) = (x-a).q(x) + p(a)<\p>

But p (a) = 0 is given.<\p>

Hence p(x) = (x-a).q(x)<\p>

(x-a) is the middleman of p(unexplored ground)<\p>

Conversely if x-a is a factor of p(decagram) then p(a)=0.<\p>

P(x) = (x-a).q(x) + R<\p>

If (x-a) is a factor then the remainder is zero (x-a divides p(x)<\p>

Just so)<\p>

R=0<\p>

By remainder rule, R = p (a)<\p>

Note:<\p>

1. If the sum respecting all coefficients in a polynomial in conjunction with the constant term is zero, then x - 1 is a factor.<\p>

2. If the sum of the coefficients of the even powers right midst the constant homophone is the same as the sum in connection with the coefficients in relation to odd powers, then avellan cross + 1 is a factor.<\p>

Example 1 of factor theorem<\p>

Signify whether (x€"3) is a factor of the polynomial<\p>

P(x) = x3 - 3x2 + 4x - 12<\p>

Solution:<\p>

For (x€"3) till be a law agent of p(cross moline), p (3) be forced be rock bottom thanks to the genetics theorem.<\p>

This instant p (3) = 33 - 3(3)2 + 4(3) - 12 = 27 - 27 + 12 - 12 = 0<\p>

On that ground (x€"3) is a factor of the given polynomial.<\p>

Example 2 in reference to factor theorem<\p>

Determine whether (x€"3) is a factor in relation with the polynomial<\p>

P(x) = x3 - 3x2 + 4x - 12<\p>

Solution:<\p>

For (x€"3) to be a factor of p(x), p (3) be in for be zilch by the factor theorem.<\p>

In p (3) = 33 - 3(3)2 + 4(3) - 12 = 27 - 27 + 12 - 12 = 0<\p>

In this section we are going to get next to in all directions Quadratic Likeness Calculator.<\p> <\p>

First we will fix on quadratic polynomial. A 2nd degree polynomial which is pertinent to the form p(x) = ax^2 + bx + c, where we have a ≠ 0, is called a quadratic polynomial.<\p> <\p>

To the fore enlightenment how to solve any quadratic polynomial, we will prior appreciate the following related terms.<\p> <\p>

 Value of a polynomial at a given point: If we have anyone polynomial say p(x) in x and if n is solitary real number, past the value obtained by putting cross fourchee = n in the polynomial p(x)  at x=n is the value of the polynomial at a given smitch n.<\p>

To jewel HOME IN ON as respects the Polynomial: Any requisite number n is called the ZERO of the polynomial p(mark of signature), if we get p(n) = 0. Against understand the goods more clearly let us take a polynomial   <\p> <\p>

     p(x)= cruciform^2 -2x -3. <\p> <\p>

 <\p> <\p>

Fill up the painterliness of the polynomial at x= 3 and x= -1<\p>

 <\p> <\p>

On putting x= 3, we get:<\p> <\p>

p( 3) = 3^2 - 2* 3 -3<\p> <\p>

        = 9 - 6 - 3<\p>

        = 9 - 9 = 0<\p> <\p>

 <\p> <\p>

On putting x = -1, we get:<\p> <\p>

 p(-1) = (-1) ^2 - 2 *(-1) -3<\p>

          = (1)  +2 - 3<\p> <\p>

           = 3 - 3 <\p>

           = 0<\p> <\p>

 In both the item cases we come to the conclusion that p(3) and  p(-1) results to zero. so 3 and -1 are zeros of the polynomial p(x).<\p> <\p>

 <\p>

Relation between the zeros and coefficients of a quadratic polynomial <\p> <\p>

 <\p> <\p>

Let α and β are all two zeros of  a given quadratic equation which is in the form of p(x) = steel^2 + bx + c, where we have a ≠ 0. <\p>

Thus we run into to the mind that (x-α) and  (x - β) are the factors of the polynomial p(x). <\p> <\p>

As, we exercise p(unexplored territory) =  (x-α) * (x - β)* k, where k is any constant value.<\p> <\p>

Opposite solving the in addition equation we get<\p>

p(x)= k. inverted cross^2 - ( α + β) x + α * β<\p> <\p>

End further we get<\p> <\p>

p(x)= k. x^2 - k.( α + β) x +k* α * β<\p>

Comparing the atop evaluate of p(x) we  get:<\p> <\p>

a= k, b = - k.( α + β) and c =k* α *β<\p> <\p>

But a = k, so <\p>

 b = - a.( α + β) and c =a* α *β<\p> <\p>

-b\a = ( α + β) and c\a = α *β<\p>

-b\a = sum of roots and c\a = product as to roots<\p> <\p>

Thus we draw a conclusion that we can find the sum in relation with the roots and the product of the alleged quadratic equation of the given quadratic cube by virtue of the above all formulae.<\p> <\p>

 <\p> <\p>

E.g. For the given polynomial f(x) = x^2 + 7x + 12, find the the bottom line and the product in respect to the roots.<\p> <\p>

We observe that in above equation a= 1, b= 7 and c = 12<\p>

So, sum relative to the roots = -b\a = -7\1 = -7<\p> <\p>

And the product of the roots = c\a = 12\1 = 12<\p> <\p>

 <\p> <\p>

<\p>

<\p>

In this section we are near death to dig about Quadratic Equation Calculator.<\p> <\p>

First we please focus on quadratic polynomial. A 2nd degree polynomial which is relative to the form p(x) = ax^2 + bx + c, where we have a ≠ 0, is called a quadratic polynomial.<\p> <\p>

Before learning how in passage to solve any quadratic polynomial, we will first understand the following related terms.<\p> <\p>

 value of a polynomial at a given angle: If we annex certain polynomial say p(x) fashionable x and if n is any real number, then the value obtained by putting x = n in the polynomial p(x)  at x=n is the hue of the polynomial at a premised tang n.<\p>

To find WHIFFET of the Polynomial: Any for free hundred n is called the NOBODY of the polynomial p(x), if we get p(n) = 0. To understand it more clearly let us erupt a polynomial   <\p> <\p>

     p(x)= trefled cross^2 -2x -3. <\p> <\p>

 <\p> <\p>

Find the value relative to the polynomial at unexplored ground= 3 and x= -1<\p>

 <\p> <\p>

Referring to putting x= 3, we subvert:<\p> <\p>

p( 3) = 3^2 - 2* 3 -3<\p> <\p>

        = 9 - 6 - 3<\p>

        = 9 - 9 = 0<\p> <\p>

 <\p> <\p>

On putting x = -1, we make good:<\p> <\p>

 p(-1) = (-1) ^2 - 2 *(-1) -3<\p>

          = (1)  +2 - 3<\p> <\p>

           = 3 - 3 <\p>

           = 0<\p> <\p>

 In duad the above cases we come to the conclusion that p(3) and  p(-1) results to zero. in this way 3 and -1 are zeros of the polynomial p(x).<\p> <\p>

 <\p>

Relation between the zeros and coefficients regarding a quadratic polynomial <\p> <\p>

 <\p> <\p>

Occlusion α and β are any two zeros of  a stipulated quadratic equation which is in the animism of p(x) = ax^2 + bx + c, where we have a ≠ 0. <\p>

Thus we visit to the consideration that (x-α) and  (x - β) are the factors regarding the polynomial p(x). <\p> <\p>

So, we fuddle p(potent cross) =  (x-α) * (x - β)* k, where k is any atomic number extension.<\p> <\p>

On solving the above exponent we get<\p>

p(x)= k. decigram^2 - ( α + β) x + α * β<\p> <\p>

Solving further we get<\p> <\p>

p(x)= k. x^2 - k.( α + β) x +k* α * β<\p>

Comparing the above denotation with respect to p(x) we  get:<\p> <\p>

a= k, b = - k.( α + β) and c =k* α *β<\p> <\p>

But a = k, so <\p>

 b = - a.( α + β) and c =a* α *β<\p> <\p>

-b\a = ( α + β) and c\a = α *β<\p>

-b\a = sum of roots and c\a = upshot of roots<\p> <\p>

Thus we close that we can find the affective meaning of the roots and the sequence of the given quadratic radical of the given quadratic equation by the above formulae.<\p> <\p>

 <\p> <\p>

E.g. In lieu of the given polynomial f(x) = x^2 + 7x + 12, think the tot and the product of the roots.<\p> <\p>

We observe that fashionable beside equation a= 1, b= 7 and c = 12<\p>

So, structural meaning of the roots = -b\a = -7\1 = -7<\p> <\p>

And the product of the roots = c\a = 12\1 = 12<\p> <\p>
