this is from me, a random high schooler

but! if you have a graphing calculator, look up quadratic formula programs! if you can get a program on your calculator that lets you put in a, b, and c then gives the roots(but probably only real answers): you can use that on the act!

also: graphing calculators take 4 triple-a batteries. almost all have easy removable backs!

you can also use it to solve the quadratic equation without a program like i mentioned. simply put it in under y=, and go to calc(2nd+graph) and do zero! you'll have to do it twice though to find both.

for absolute value: press math, go to num, and then abs(, put the equation in. like |2x-5| is abs(2x-5)

Math Resources

I have a nice resource page on my site to help Math people find calculators, widgets, and other helpful websites. I currently teach highschool Math and have three children taking high level Math classes and I undestand that when it is homework time we all need to find helpful Math information.

Here is a short list of items you can find on my page

Helpful websites
