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
