Complete the Squares, and make use of the standard form of the finished equation.

-----THE MISTAKE HERE-.



------This will not work. This is not a real circle.
---No good.

Look for any mistakes in your given equation or in my steps. I found none in mine but examine if you want.

 ------- Grouping variables

 





Since the center-radius form of the equation of a circle is: ,

it's obvious that the center, or (h, k) = (, 2)

Since , then r, or radius = , or 

Based on this info, you should be able to graph the circle.
