Yes, but I think your teacher expects you to simplify.
Use a common denominator, x%2B1
F%28x%29%2BG%28x%29=x%2F%28x%2B1%29+%2B+%28%28x%5E2-1%29%28x%2B1%29%29%2F%28x%2B1%29
F%28x%29%2BG%28x%29=%28x%2B%28x%5E2-1%29%28x%2B1%29%29%2F%28x%2B1%29
F%28x%29%2BG%28x%29=%28x%2B%28x%5E3%2Bx%5E2-x-1%29%29%2F%28x%2B1%29
F%28x%29%2BG%28x%29=%28x%5E3%2Bx%5E2-1%29%2F%28x%2B1%29
