(x+8)^2+(y+9)^2=256

(x + 8)^{2} + (y + 9)^{2} = 256

(a, b) = (- 8, - 9), r = 16

Solution steps

(x + 8)^{2} + (y + 9)^{2} = 256

Rewrite

(x + 8)^{2} + (y + 9)^{2} = 256

in the form of the standard circle equation

(x - (- 8))^{2} + (y - (- 9))^{2} = 1 6^{2}

Therefore the circle properties are:

(a, b) = (- 8, - 9), r = 16

x^{2} + y^{2} + 2 x - 6 y = 26

x^{2} + 3 x + y^{2} + 8 x = 25

x^{2} + y^{2} + 1 x - 4 y - 8 = 0

x^{2} + (y + 4)^{2} = \frac{3}{5}

(X - 3)^{2} + (Y + 1)^{2} = 6
