The Quadratic Formula

Explanation, Video, YouTube
Before the method of completing the square was developed, only very limited types of quadratic equations could be solved. This method eliminated those limitations, allowing the solutions of any quadratic equation to be found.
This lecture shows how the 'quadratic formula' can be derived from the process of completing the square, and show why the quadratic formula is so useful.
