x^2-25-6x+9+y^2=0

x^{2} - 25 - 6 x + 9 + y^{2} = 0

(a, b) = (3, 0), r = 5

Solution steps

x^{2} - 25 - 6 x + 9 + y^{2} = 0

Rewrite

x^{2} - 25 - 6 x + 9 + y^{2} = 0

in the form of the standard circle equation

(x - 3)^{2} + (y - 0)^{2} = 5^{2}

Therefore the circle properties are:

(a, b) = (3, 0), r = 5

x^{2} + y^{2} - 2 x + 4 y - 11 = 0

x^{2} + y^{2} - 12 x + 8 y - 48 = 0

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

(x + 5)^{2} + (y - 2)^{2} = 9

x^{2} + y^{2} = 125
