can anyone help me with this integration(adsbygoogle = window.adsbygoogle || []).push({});

integral (dx)/(x^3+x)

i tried solving it with partial integration and got stuck when i got find B and C...this was what i did

= integral (dx)/[x(x^2 + 1)]

= 1/[x(x^2 - 1)] = A/x + (Bx+C)/(x^2 + 1)

=> 1 = A(x^2 + 1) + (Bx+C)(x)

=> 1 = Ax^2 +A + Bx^2 + Cx

A = 1

then i got stuck here on how to get the B and C variable

Thanks in advance to those who can help
