x^2+4x+y^2-14y=-3

x^{2} + 4 x + y^{2} - 14 y = - 3

(a, b) = (- 2, 7), r = 52

Solution steps

x^{2} + 4 x + y^{2} - 14 y = - 3

Rewrite

x^{2} + 4 x + y^{2} - 14 y = - 3

in the form of the standard circle equation

(x - (- 2))^{2} + (y - 7)^{2} = (52)^{2}

Therefore the circle properties are:

(a, b) = (- 2, 7), r = 52
