Question

hi.. please I need this:
indefinite integration of(x^2 + 2x + 1 / x^2 + 1)

Answer 1

indefinite integral of (x^2+2x+1)/(x^2+1)
indefinite integral of (x+1)(x+1)/(x+1)(x-1)
indefinite integral of (x+1)/(x-1)

I feel bad, but after this I can't quite finish the integration

Answer 2

long division\[\frac{x^2+2x+1}{x^2+1}=1+\frac{2x}{x^2+1}\]now integrate

Answer 3

thanks
