Beliebt Geometry >

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

Lösung

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

Lösung

(a, b) = (1, - 2), r = 3

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

(x - 1)^{2} + (y - (- 2))^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (1, - 2), r = 3
