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.

**Jai**, Thursday, May 5, 2011 at 12:57amyes, you got the right answer for simplifying it.

2/(x^2-16) + 3/(x^2 -2x-8) = 5x+16/(x-4)(x+4)(x+2)

but the question says that if numerator is equal to 6, what is x? thus we equate the numerator to 6:

5x + 16 = 6

5x = 6-16

5x = -10

x = -2

hope this helps~ :)
