    Integration

    The question : Integrate (x^3+1)/(x^2+x+4)^2 dx .

    Okay, so I used partial fractions and obtained (x-1)/(x^2+x+4) + (-3x +5)/(x^2+x+4)^2 .

    After further integrations, I'm stuck with one part of the integration , that is 1/(x^2+x+4)^2 . Is there any way to proceed from here ?

    Complete the square and then change the variable of integration.
