Hello, I need help integrating a rational function using partial fractions. I'm not sure how to make an integral sign on the computer or w/e, but its:
integral of (x-3)/((x^2+2x+4)^2) dx
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.
