Given the radius and the center determine the equation of a circle

The video tutorial explains how to write the equation of a circle when the center is not at the origin. It introduces the formula, identifies the center as HK, and demonstrates plugging values into the equation. The process of simplifying the equation is shown, resulting in the final circle equation.

Explain how subtracting a negative affects the equation of the circle.

What is the final equation of the circle derived from the given values?
