Beliebt Geometry >

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

Lösung

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

Lösung

(a, b) = (2, - 1), r = 5

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

(x - 2)^{2} + (y - (- 1))^{2} = (5)^{2}

Therefore the circle properties are:

(a, b) = (2, - 1), r = 5
