Beliebt Geometry >

x^2+y^2-4x+8y-12=0

Lösung

x^{2} + y^{2} - 4 x + 8 y - 12 = 0

Lösung

(a, b) = (2, - 4), r = 42

Schritte zur Lösung

x^{2} + y^{2} - 4 x + 8 y - 12 = 0

Rewrite

x^{2} + y^{2} - 4 x + 8 y - 12 = 0

in the form of the standard circle equation

(x - 2)^{2} + (y - (- 4))^{2} = (42)^{2}

Therefore the circle properties are:

(a, b) = (2, - 4), r = 42

x^2+y^2+7.2x+8.6y=2.19

x^{2} + y^{2} + 7.2 x + 8.6 y = 2.19

x^{2} + (y - 3)^{2} = 20

(x+20)^2+(y-30)^2=225

(x + 20)^{2} + (y - 30)^{2} = 225

x^2+y^2+14x+12y=-21

x^{2} + y^{2} + 14 x + 12 y = - 21

x^{2} + (y - 3)^{2} = 15
