Question 31342: Some students simplify 2x^2 - 32 / X - 4 as
(2x) (8)
2x^2 - 32
---------------------- = 2x -8
(X - 4) <-- Cancels

Chose values of X to show this is not true. Then simplify correctly.

You can put this solution on YOUR website!
i do not really understand why you're trying to show how to simplify it, so i will let you fill in the numbers and solve....but i will simplify:
(2x^2 - 32) / (x - 4)
2(x^2 - 16) / (x - 4)
(2(x-4)(x+4))/(x-4)
2(x+4) or 2x+8
