Detail solution
  1. Integrate term-by-term:

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

      1. The integral of is when :

      So, the result is:

    1. The integral of is when :

    The result is:

  2. Now simplify:

  3. Add the constant of integration:


The answer is:
