$$\int\limits_{0}^{1} \left(x + 3\right) e^{x^{2} + 6 x + 1}\, dx$$
Detail solution
  1. 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 the exponential function is itself.

      So, the result is:

    Now substitute back in:

  2. Now simplify:

  3. Add the constant of integration:


The answer is:
