x^2+y^2+6x+8x=-16

x^{2} + y^{2} + 6 x + 8 x = - 16

(a, b) = (- 7, 0), r = 33

Solution steps

x^{2} + y^{2} + 6 x + 8 x = - 16

Rewrite

x^{2} + y^{2} + 6 x + 8 x = - 16

in the form of the standard circle equation

(x - (- 7))^{2} + (y - 0)^{2} = (33)^{2}

Therefore the circle properties are:

(a, b) = (- 7, 0), r = 33

x^{2} + y^{2} - 10 x - 6 y + 25 = 0

x^{2} + y^{2} > 1

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

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

x^{2} + y^{2} - 6 x + 4 y - 12 = 0
