Since the denominator is not easily factorable and PFD does not help much, we can try completing the square. Now, let Now, it's just a matter of ln and arctan.
how would you evaluate the integral if the denominator was squared: (x^2 + 2x + 4)^2
On post #2 was told that now you have to compute Put and the integral becomes Now, for this one, put and the integral becomes, Now put everything together and we get,
