How to Solve Quadratic Equations by Completing the Square | Algebra 2

In this maths tutorial, we showed how to solve quadratic equations by Completing the Square in a step by step approach. Firstly, we established the validity of the completing the square method by comparing it with factorisation method, then we showed that Completing the Square method works especially for quadratics that do not factorise.
