I want to integrate: 1/[(x + 1)*(x^2 + x +1)] dx Now the quadratic has complex routes, and we have not done any integration with that yet, so I broke it up into its partial fractions. A/(x +1) + (Bx + C)/(x^2 + x +1) But I cannot seem to find the numbers A B C. mamybe I am just missing something real obvious?? Any pointers in the right direction? Cheers guys. PS. Is the proof of the theory that you can break up fractions like that beyond a first year math for science course?
