Solving a quadratic by completing the square

The video tutorial explains how to solve quadratic equations by completing the square. It begins with transforming the equation from standard form to vertex form, allowing the use of inverse operations. The process involves creating a perfect square trinomial by adjusting the constant term. The tutorial emphasizes balancing the equation by adding the same value to both sides. It then demonstrates factoring the trinomial into a binomial square and solving for X using inverse operations. The final solution is presented as two possible values for X, derived from the square root operation.
