try substitution
t=x^2
dt=2xdx
1/2dt=xdx

can i do partial fraction method?

\[\int\limits \frac{ 2 }{ x (x^2+1)^2} dx\]
Hmm. Use partial fractions?

\[2\left( \frac{ 1 }{ 2(x^2+1) }-\frac{ 1 }{ 2 }\log(x^2+1)+\log x \right)\]

but for me personal i prefer the first method present by sami....

okay thank you!

you're welcome

did u solve the problem?
