Beliebt Geometry >

x^2-2x+y^2+2y=7

Lösung

x^{2} - 2 x + y^{2} + 2 y = 7

Lösung

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

Schritte zur Lösung

x^{2} - 2 x + y^{2} + 2 y = 7

Rewrite

x^{2} - 2 x + y^{2} + 2 y = 7

in the form of the standard circle equation

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

Therefore the circle properties are:

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