I've tried using the method for repeated irreducible quadratic factors, but it seems to return the same function. Then I tried substituting u=x+1 and some other things but they didn't seem to get me anywhere; I tried splitting the numerator into 2 different integrals but I can't seem to figure it out that way either. Any help would be appreciated, thanks.
