x^2+y^2+4x-2y-4=0

Lösung

x^{2} + y^{2} + 4 x - 2 y - 4 = 0

Lösung

(a, b) = (- 2, 1), r = 3

Schritte zur Lösung

x^{2} + y^{2} + 4 x - 2 y - 4 = 0

Rewrite

x^{2} + y^{2} + 4 x - 2 y - 4 = 0

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (- 2, 1), r = 3

x^{2} + 10 x + y^{2} - 16 y - 11 = 0

36x^2-36x+36y^2+72y=279

36 x^{2} - 36 x + 36 y^{2} + 72 y = 279

x^2-6x+y^2-2y+6=0

x^{2} - 6 x + y^{2} - 2 y + 6 = 0

(x+4)^2+(y-4)^2=9

(x + 4)^{2} + (y - 4)^{2} = 9

(x-3)^2+(y+4)^2=25

(x - 3)^{2} + (y + 4)^{2} = 25
