Beliebt Geometry >

x^2+y^2+2x-2y-1=0

Lösung

x^{2} + y^{2} + 2 x - 2 y - 1 = 0

Lösung

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

Schritte zur Lösung

x^{2} + y^{2} + 2 x - 2 y - 1 = 0

Rewrite

x^{2} + y^{2} + 2 x - 2 y - 1 = 0

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

(x-1)^2+(y-5)^2=36

(x - 1)^{2} + (y - 5)^{2} = 36

2 x^{2} + 2 y^{2} = 24

(x - 8)^{2} + y^{2} = 7

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

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

(x-1)^2+(y-4)^2=16

(x - 1)^{2} + (y - 4)^{2} = 16
