9=x^2-6x+9+y^2+4y+4

9 = x^{2} - 6 x + 9 + y^{2} + 4 y + 4

(a, b) = (3, - 2), r = 3

Solution steps

9 = x^{2} - 6 x + 9 + y^{2} + 4 y + 4

Rewrite

9 = x^{2} - 6 x + 9 + y^{2} + 4 y + 4

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (3, - 2), r = 3

4 x^{2} + 4 y^{2} = 256

3 x^{2} + 3 y^{2} - 6 x + 3 y - 4 = 0

2 x^{2} + 2 y^{2} = \frac{1}{2}

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

2 x^{2} + 2 y^{2} - 20 x + 8 y + 34 = 0
