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. Integrate term-by-term:

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

        But the integral is

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