Complete the square to write the equation of the circle in standard form. Then graph the circle.
x2 + y2 – 6x + 6y + 9 = 0
STEP 1: Group terms, first x and then y.
(
) + (
) =

STEP 2: Complete the square.
( x2 − 6x + ) + (y2 + 6y + ) =

STEP 3: Write in standard form by factoring.
( x + )2 + (y + )2 =

STEP 4: Find the center and the radius of the circle.
center = ( , )
radius =
