To divide the function f(x) by (x^2-4x-12), we find that the quotient is Q(x) and the remainder is (x+6). If f(-2)=a and f(6)=b, what is the value of b/a?

Welcome to AAC. Since this is your 1st post you may have missed reading about how this works. This is Homework Help, which is not the same thing as Homework Done For You. You need to show what can do to get started and then we will guide you toward the solution. So what can you tell us about dividing one polynomial by another and specifically what knowing the remainder of the division tells you?

What i would suggest is that you write this all out as if you had to in order to solve it, as if you knew the numerator too. Then see how easy it is to solve.
Write out the two functions entirely and see what you can figure out.

I think he was expecting Homework Done for Him. 'tis a pity.
