Completing the Square Concepts

The video tutorial explains how to find the value of c to complete the square in a quadratic equation. The process involves ensuring the coefficient a is 1, then taking the value of b, dividing it by 2, and squaring it to find c. An example is provided where b is -3, resulting in c being 9/4. This value allows the quadratic to be expressed as a perfect square binomial, facilitating further mathematical applications.
