I can't get the right answer to this problem...what am I doing wrong?
(2x4)(x+1)^2
(2x4)(x^2+2x+2)
2x^3+4x^2+4x4x^28x8
2x^34x8 but the answer I'm supposed to get is 2x^36x4
what am I doing wrong? Please help! thanks

PsyDAG,
(x + 1)^2 = x^2 + 2x + 1
You added to get the last term rather than multiplying.
