Similarly, to my previous problem. I solved the problem and got an answer, but it says it's the incorrect answer.

The problem is:

I set the equation to be:

x^3 + 17 = A(x+1) + B(x+3)

I solved for A first and got5.

I then went back and solved for B and got8.

This would result in the partial fraction of:

I then integrated and got:

5 ln |x+1| + 8 ln |x+3|

Can anyone show me how it is correctly done?

Thank you.
