The equation of a circle is defined by: (x - h)² + (y - k)² = r² where
(h,k) represents the center of your circle and r = the radius
So (x - 2)² + (y + 8)² = 121 is your equation
Here are some examples of how the Quadratic Formula works:
<span>Solve <span>x2 + 3x – 4 = 0</span></span>
This quadratic happens to factor:
x2 + 3x – 4 = (x + 4)(x – 1) = 0
.
Then, as expected, the solution is <span>x = –4, x = 1</span>.
