Beliebt Geometry >

x^2+4x+y^2-2y=-1

Lösung

x^{2} + 4 x + y^{2} - 2 y = - 1

Lösung

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

Schritte zur Lösung

x^{2} + 4 x + y^{2} - 2 y = - 1

Rewrite

x^{2} + 4 x + y^{2} - 2 y = - 1

in the form of the standard circle equation

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

Therefore the circle properties are:

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