Homework Help: Algebra

Posted by Algebra on Thursday, May 5, 2011 at 12:48am.

Add and simplify:
2/x^2-16 + 3/x^2 -2x-8

Now if the numerator of your answer equals 6, what does x equal?

My answer of 5x+16/(x-4)(x+4)(x+2) does not match theirs. The correct answer is -2. I don't know how they got there.
