The technique of completing the square is used to turn a quadratic into the sum of a squared binomial and a number: (x – a)2 + b. The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.

But circle equations are often given in the general format of ax2 + by2 + cx + dy + e = 0, When you are given this general form of equation and told to find the center and radius of a circle, you will have to "complete the square" to convert the equation to center-radius form
