x^2+y^2-4x+2y-11=0

Lösung

x^{2} + y^{2} - 4 x + 2 y - 11 = 0

Lösung

(a, b) = (2, - 1), r = 4

Schritte zur Lösung

x^{2} + y^{2} - 4 x + 2 y - 11 = 0

Rewrite

x^{2} + y^{2} - 4 x + 2 y - 11 = 0

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (2, - 1), r = 4

(x-8)^2+(y-2)^2=4

(x - 8)^{2} + (y - 2)^{2} = 4

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

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

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

x^2-6x+y^2+8y-11=0

x^{2} - 6 x + y^{2} + 8 y - 11 = 0

x^2+y^2-8x+6y-11=0

x^{2} + y^{2} - 8 x + 6 y - 11 = 0
