Completing the square to convert between quadratic and vertex form

The video tutorial explains how to convert a quadratic equation into vertex form by completing the square. It begins with an introduction to the vertex form and the necessity of completing the square. The instructor then demonstrates factoring out a coefficient and adjusting terms to create a perfect square trinomial. The process involves adding and subtracting terms while considering the impact of multiplication on the equation. Finally, the tutorial concludes with the equation in vertex form, highlighting the vertex and transformations of the graph.
