Indefinite integration by Completing the Square Problems and Solutions

In indefinite integral calculus, completing the square method is used in some cases for finding the indefinite integration for the functions when there is only one way to convert the quadratic expressions into the square form completely. So, let’s learn how to find the integration by the completing the square method from the following indefinite integration questions.
