x^2+y^2+14x-2y=225

x^{2} + y^{2} + 14 x - 2 y = 225

(a, b) = (- 7, 1), r = 511

Solution steps

x^{2} + y^{2} + 14 x - 2 y = 225

Rewrite

x^{2} + y^{2} + 14 x - 2 y = 225

in the form of the standard circle equation

(x - (- 7))^{2} + (y - 1)^{2} = (511)^{2}

Therefore the circle properties are:

(a, b) = (- 7, 1), r = 511

- x^{2} - y^{2} + 5 = x + y + 1

x^{2} + y^{2} + 8 x - 6 y = 6

x^{2} - 8 x + y^{2} - 2 y - 19 = 0

(x + 5)^{2} + (y + 0.6666600000000 \dots)^{2} = 0.4444400000000 \dots

x^{2} + y^{2} = 19.4 x + 3 y - 4
