The conic section for the equation x^2 - 4x + y^2 - 4y + 4 = 12 is a circle.

x^2 - 4x + y^2 - 4y + 4 = 12

(x^2 - 4x + 4) + (y^2 - 4y + 4) = 12 + 4

(x - 2)^2 + (y - 2)^2 = 16

it is a circle with center (2, 2) and radius = 4.

x^2 - 4x + y^2 - 4y + 4 = 12

(x^2 - 4x + 4) + (y^2 - 4y + 4) = 12 + 4

(x - 2)^2 + (y - 2)^2 = 16

it is a circle with center (2, 2) and radius = 4.

(5a - 7)(2a - 1)

= 10a^2 - 5a - 14a + 7

= 10^2 - 19a + 7

= 10a^2 - 5a - 14a + 7

= 10^2 - 19a + 7

The equation of the circle whose center is at (2, 1) and radius is 3 is
**Weegy:** First know the equation of a circle. (x-h)^2 + (y-k)^2 = r^2. Now it becomes easy. You plug in 5 for x and 6 for y. You plug in 3 for r. That will be your equation. (5-h)^2 + (6-k)^2 = 9. (More)
