(x-2)(x+2)(x-4)original problem

1.x^2 + 2x-2x=x^2-4)

2. (x^2-4)(x-4)

3. x^3-4x^2-4x+16=0

the first step should be x^2+2x-2x-4 = x^2-4(I forgot to put the (-4)

So far, so good.

(x^2-4)(x-4) = x^3 - 4x^2 - 4x + 16

You don't need an equation, just the polynomial.

Is that in simplest form or am I suppose to do something else with it? It seems too easy-
