Detail solution
  1. The integral of a constant times a function is the constant times the integral of the function:

    1. Rewrite the integrand:

    2. Let .

      Then let and substitute :

      1. The integral of a constant times a function is the constant times the integral of the function:

        1. The integral of is .

        So, the result is:

      Now substitute back in:

    So, the result is:

  2. Add the constant of integration:
