We will proceed to convert the equations into standard format to determine the solution.

we know that

The Standard Form Equation of a Circle is equal to

where

(h,k) is the center of the circle

r is the radius of the circle

__Case N __

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square twice. Remember to balance the equation by adding the same constants to each side.

Rewrite as perfect squares

__Case N __

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square twice. Remember to balance the equation by adding the same constants to each side.
