solve

A)p(x)= x(x+2)(x-4)
b)p(x)=(x+2)^3(x-1)

Are they two different problems or one problem.

If just one problem and you are simplifying:

Multiply (x+2) times (x-4) then multiply that trinomial by x

for the second one..

Multiply (x+2)(x+2)

multiply that trinomial times x+2 again

then multiply that answer by x -1
