I'm assuming that the problem is right???


Recall that if , then




In your case, , which means that and


Now derive f and g to get: and



Now plug these functions into the formula to get:





Now multiply every term by the inner LCD x+2 and simplify






you could perform more simplifications, but that would only change how the answer looks.
