Question

How do you integrate `(x^2 + 2x -5) / [(x - 2)*(x+1)*(x^2+1)]`?

Answer 1

`1/5 ln |x - 2| + ln |x+1| + 8/5 arc tan x - 3/5 ln |x^2 + 1| + C`

Explanation:

I am not 100% sure for this one but I have attached a picture so that you may see what I did.
Please, feel free to ask any questions and even more, to correct what I did wrong :)
