x^2+14x+12y+y^2=-21

x^{2} + 14 x + 12 y + y^{2} = - 21

(a, b) = (- 7, - 6), r = 8

Solution steps

x^{2} + 14 x + 12 y + y^{2} = - 21

Rewrite

x^{2} + 14 x + 12 y + y^{2} = - 21

in the form of the standard circle equation

(x - (- 7))^{2} + (y - (- 6))^{2} = 8^{2}

Therefore the circle properties are:

(a, b) = (- 7, - 6), r = 8

3 x^{2} + 3 y^{2} + 18 x - 24 y + 63 = 0

(x + 1)^{2} + (y + 8)^{2} = 14

(x - \frac{1}{2})^{2} + (y)^{2} = \frac{1}{4}

(x - 5)^{2} + (y + 5)^{2} = 9

(x)^{2} + (y)^{2} = 9
