∫x^2/(4x+1)^10 dx
i know that solving this is possible by partial fractions like A/4x+1 + (Bx+C)/(4x+1)^2 + (Dx+E)/(4x+1)^3
and so on but i would like to know if there is another way of solving this.

Partial integration can give you similar terms without solving large systems of equations.

I would substitute ##4x+1=u## which makes the entire quotients a lot easier.
