Beliebt Geometry >

(x^2-4x)+(y^2+2y)=31

Lösung

(x^{2} - 4 x) + (y^{2} + 2 y) = 31

Lösung

(a, b) = (2, - 1), r = 6

Schritte zur Lösung

x^{2} - 4 x + (y^{2} + 2 y) = 31

Rewrite

x^{2} - 4 x + (y^{2} + 2 y) = 31

in the form of the standard circle equation

(x - 2)^{2} + (y - (- 1))^{2} = 6^{2}

Therefore the circle properties are:

(a, b) = (2, - 1), r = 6
