Definite Integral with tricky deniminator

  1. Nov 25, 2012 #1
    1. The problem statement, all variables and given/known data

    I attached problem as a picture.

    2. Relevant equations

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

    3. 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?

    There is a much easier way. Try a substitution.
