MHB Proving Equivalence of f(x) and g(x)

[pappoelarry]

Consider the two functions f(x)=(x-1)(x4+x³+x²+x+1) and g(x)=x5-1. If they are equivalent, prove they are; if they are not equivalent, prove they aren't.

Multiply out f(x). What do you get?

Can you multiply out polynomials? [math](x - 1)(x^2 + x + 1) = x(x^2 + x + 1) - (x^2 + x + 1) = x^3 + x^2 + x - x^2 - x - 1 = x^3 - 1[/math] for example.

Step one: take an Algebra Course!

(Where did you get this problem?)

First step- take an eighth or nineth grade (13 or 14 year old) algebra class!
