How to use completing the square to solve a quadratic equation

The video tutorial explains the process of completing the square, a method used to solve quadratic equations when factoring is not possible. It begins by setting the equation to zero, then demonstrates how to create a perfect square trinomial by using the B/2 squared method. The tutorial concludes with solving the equation using the square root method, resulting in a solution for X.
