x^2+y^2-4x-6y-36=0

x^{2} + y^{2} - 4 x - 6 y - 36 = 0

(a, b) = (2, 3), r = 7

Solution steps

x^{2} + y^{2} - 4 x - 6 y - 36 = 0

Rewrite

x^{2} + y^{2} - 4 x - 6 y - 36 = 0

in the form of the standard circle equation

(x - 2)^{2} + (y - 3)^{2} = 7^{2}

Therefore the circle properties are:

(a, b) = (2, 3), r = 7

(x + 9)^{2} + (y - 8)^{2} = 81

x, x^{2} + Y (x)^{2} = 100 + 5 Y

2 x^{2} + 2 y^{2} + 12 x - 8 y + 14 = 0

x^{2} + y^{2} + 6 x - 12 y + 40 = 0

(x + 9)^{2} + (y - 8)^{2} = 64
