Quick Algebra Problem

0 Hi, everyone.
I'm about to take the TEAS, and I got most of the math right on my practice tests, but this one is throwing me:
(x2+4x+4)(x26x+9)
Those are supposed to be x squared, by the way.
My ATI book for the TEAS V says the answer is 10x5, but I can only get 2x5. I'd appreciate any help anyone could give me!
Thanks!Last edit by susurra on Nov 29, '10

Distribute the negative in the second half and add subtract like terms:
x^2 + 4x +4 x^2 + 6x  9
4x + 4 + 6x  9
10x  5
