Question

use the foil method
(^3+2x^2)(x^2+3-x)

Answer 1

In your first binomial, what is being cubed?

Answer 2

you cant foil with trinomals (or anything other than 2 bimomials really); the mnumonic breaks down and simply makes no sense.

Answer 3

multiply, like you learned back in the 3rd grade; is all you need to do
