Beliebt Geometry >

x^2+y^2-4x+8y+4=0

Lösung

x^{2} + y^{2} - 4 x + 8 y + 4 = 0

Lösung

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

Schritte zur Lösung

x^{2} + y^{2} - 4 x + 8 y + 4 = 0

Rewrite

x^{2} + y^{2} - 4 x + 8 y + 4 = 0

in the form of the standard circle equation

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

Therefore the circle properties are:

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

(x-1)^2+(y+3)^2=16

(x - 1)^{2} + (y + 3)^{2} = 16

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

x^2+y^2-6x-4y=36

x^{2} + y^{2} - 6 x - 4 y = 36

x^2+y^2+6x-4y+12=0

x^{2} + y^{2} + 6 x - 4 y + 12 = 0

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