I have the following problem:

My logic is that since I am given one of the values which was divided by, if I multiply by that value I should get the other value.

I tried multiplying (f/g)(x) with f(x) and this is what I did:

I got (x+8) after simplifying the above ^. However, (x+8) does not equal g(x)..

Any help would be greatly appreciated with this problem. Thank you very much in advance (:
