Beliebt Geometry >

x^2+y^2+4x+8y-80=0

Lösung

x^{2} + y^{2} + 4 x + 8 y - 80 = 0

Lösung

(a, b) = (- 2, - 4), r = 10

Schritte zur Lösung

x^{2} + y^{2} + 4 x + 8 y - 80 = 0

Rewrite

x^{2} + y^{2} + 4 x + 8 y - 80 = 0

in the form of the standard circle equation

(x - (- 2))^{2} + (y - (- 4))^{2} = 1 0^{2}

Therefore the circle properties are:

(a, b) = (- 2, - 4), r = 10
