f'(x)= (2+x^2)/(1+x^2) Find anti derivative

2. Relevant equations

3. The attempt at a solution

I attempted to bring the denominator up using (1+x^2)^-1 and i also tried long division to simplify but had no luck...

1/(1+x^2) is the inverse tan derivative, but what can i do from here:

(2+x^2) * 1/(1+x^2) is substitution legal here?
