x^2+y^2+14x-12y=-81

x^{2} + y^{2} + 14 x - 12 y = - 81

(a, b) = (- 7, 6), r = 2

Solution steps

x^{2} + y^{2} + 14 x - 12 y = - 81

Rewrite

x^{2} + y^{2} + 14 x - 12 y = - 81

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (- 7, 6), r = 2
