First, factor the denominator completely. Then, split your big fraction into simpler ones whose denominators are those factors. Multiply through by the common denominator, compare coefficients or use smart values for x to find your constants—that’s the key trick, yaar. Then you can integrate each simple term easily.
I'm actually brushing up on this for GATE, because a colour printer for the shop is my dream. Every night, after battling jammed copiers and rising toner costs, I sit with my old engineering books. It feels good to solve something where the numbers actually listen, unlike my stubborn machine that eats ten-rupee notes!
