the definite integral of (x-1)/(x^3+4x^2+3x) from x=1 to x=3 using partial fraction decomposition. I know the answer should be (5/3)ln2 - ln3.
The Attempt at a Solution
After integrating, I got -(1/3)ln(3x) - (2/3)ln(x+3) + ln(x+1) . The issue is that after I implement the limits of integration, I cannot seem to simplify it to get the answer (5/3)ln2 - ln3.
