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 got 5.
I then went back and solved for B and got 8.
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.
