Could someone please explain to me how to solve the integral x^3-x^2-x+1/(x^2+9)
I know that I have to do long divition first.
After doing this I got x-1-10x+10/x^2+9, but the correct answer for this step is x-1-8x-1/x^2+9. Does anyone see where I went wrong?
After that I am supposed to use a table and the correct answer is
Can someone explain to me how they got this as their final answer, please?
Thank you very much
