Learn how to graph circles when the equation is written in general form! In this lesson, we’ll walk step-by-step through how to rewrite equations by completing the square so you can easily identify the center and radius of a circle.
We start with a simple example, then move on to a more challenging problem that requires a few extra steps. By the end, you’ll feel confident turning general form equations into standard form and graphing circles accurately.
This video is perfect for Algebra 2 and Precalculus students who want a clear and practical approach to graphing circles.
