Hi just wondered how to integrate this ∫(x+2)/(x²+1) im making (x+2)ln(x²+1) doesn't look right lol

Separate into two integrals: $\displaystyle \int \frac{x}{x^{2}+1}\,\,dx + \int \frac{2}{x^{2}+1}\,\,dx$ $\displaystyle \frac{ln(x^{2}+1)}{2} + C_{1} + 2tan^{-1}(x) + C_{2}$ $\displaystyle \frac{ln(x^{2}+1)}{2} + 2tan^{-1}(x) + C$
