Homework Statement



I attached problem as a picture.

Homework Equations



I know that the integral of 1/x equals lnx if the derivative of the denominator is equal to the numerator.

The Attempt at a Solution



I tried to foil out the denominator and integrate by parts but it was very difficult. Is there an easier way?
