9x^2+9y^2+12x+36y=104

9 x^{2} + 9 y^{2} + 12 x + 36 y = 104

(a, b) = (- \frac{2}{3}, - 2), r = 4

Solution steps

9 x^{2} + 9 y^{2} + 12 x + 36 y = 104

Rewrite

9 x^{2} + 9 y^{2} + 12 x + 36 y = 104

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (- \frac{2}{3}, - 2), r = 4

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

(9 x - 3)^{2} + (9 y + 12)^{2} = 172

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

x^{2} + y^{2} - 6 x - 8 y - 50 = 0

x^{2} + y^{2} - 2 x - 2 y - 11 = 0
