x^2+y^2+6x=16

x^{2} + y^{2} + 6 x = 16

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

Solution steps

x^{2} + y^{2} + 6 x = 16

Rewrite

x^{2} + y^{2} + 6 x = 16

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)} + 25 x + 10 y = - 12

x^{2} + y^{2} + 14 x - 20 y + 100 = 0

x^{2} + 6 x + y^{2} - 8 y - 75 = 0

(x + 2)^{2} + (y + 8)^{2} = 100

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