Completing the square often feels like a set of steps to memorize, but it is really a geometric idea. In this video, we solve quadratic equations by literally building a square and watching the algebra fall into place.
Starting with a simple quadratic, we use area models to show why splitting the linear term works, where the extra number comes from, and how the equation turns into a perfect square. This visual approach makes the method easier to understand and easier to remember.
If you have ever wondered why completing the square works, or where the quadratic formula comes from, this video is for you.
