What is the standard form of the equation of a circle?
(x + h)² + (y + k)² = r²
x² + y² = r²
(x - h)² + (y - k)² = r²
(x - h)(y - k) = r²

Given the center (3, -2) and radius 5, write the equation of the circle.
(x + 3)² + (y - 2)² = 20
(x - 3)² + (y + 2)² = 30
(x + 3)² + (y + 2)² = 25
(x - 3)² + (y + 2)² = 25

Convert the equation x^2 + y^2 - 6x + 4y - 12 = 0 to standard form.
(x + 3)^2 + (y - 2)^2 = 16
(x + 3)^2 + (y + 2)^2 = 30
(x - 3)^2 + (y - 2)^2 = 20
(x - 3)^2 + (y + 2)^2 = 25
