Detail solution

  1. Rewrite the integrand:

  2. Integrate term-by-term:

    1. Don't know the steps in finding this integral.

      But the integral is

    1. The integral of a constant is the constant times the variable of integration:

    The result is:

  3. Now simplify:

  4. Add the constant of integration:

The answer is:
