How do I integrate this /sci/?
I've tried integration by parts but end up with even uglier integrals containing arctan (x)
I also tried substitution but couldn't find an appropriate term to substitute
Pls help
Partial fraction decomposition.
Trig substitution. The -2x/(x^2+1) integrates to tangent

What exactly would you substitute? I tried using the fact that 1/(1+x^2) integrates to arctan(x) with integration by parts but that left me with even uglier integrals

The first reply already gave you the answer, faggot. Delete this thread and then delete yourself.

Such madness for so little reason

This is correct. x^2+2x+1 can be factored (x+1)^2. Decompose that into 3 fractions and integrate the result.

I'm stuck on a similar problem, but with complex integrals. How do I into partial fraction decomposition?

OP here, thanks that explains it really well
Multiply bottom out? Get rid of denominator? Then it should be a trivial problem.
