Homework Statement



Calculate:

\integral \frac{1}{(x^2+1)(x+1)}


Homework Equations



\integral f(x) g'(x) = f(x) g(x) - \integral f'(x) g(x) + C

The Attempt at a Solution



I've tried using both 1/(x+1) and 1/(x^2 + 1) as dv, but both end up in another integral I can't solve, one with -ln(x+1) 2x / (x^2+1)^2 and the other with -atan(x)/(x+1)^2.

I think that probably this can only be solved with the method for rational functions (with all the coefficients), but I'm not sure.

Using partial fractions is much better idea.

Thanks for answering. I know it's much better, but I'm solving some tests (same format) and the position in which this one appears is the "integration by parts question".
