Represent the function equivalently in the form


%28x%5E2-3x%29%2F%28x%2B1%29 = %28x%5E2+%2B+x%29%2F%28x%2B1%29%29 - %284x%29%2F%28x%2B1%29 = %28x%2A%28x%2B1%29%2F%28x%2B1%29%29 - %284x%2B4%29%2F%28x%2B1%29 + 4%2F%28x%2B1%29 = x - 4 + 4%2F%28x%2B1%29.


The first two terms produce the "table integrals".


The third term integral  is  4*log(|x+1|).


Do not forget to include the "arbitrary constant term C" in your final answer (!)
