1. The problem statement, all variables and given/known data I need to integrate (2x-5)/(x^2+5x+11) 2. Relevant equations 3. The attempt at a solution My problem is just finding a formula for an irreducable quadratic. I know if the denominator was x(x^2+1), I would use A/x+(Bx+C)/(x^2+1). I just don't know the formula in this case and I feel like I could solve it if I had a formula.
