Beliebt Geometry >

x^2+y^2-4x-21=0

Lösung

x^{2} + y^{2} - 4 x - 21 = 0

Lösung

(a, b) = (2, 0), r = 5

Schritte zur Lösung

x^{2} + y^{2} - 4 x - 21 = 0

Rewrite

x^{2} + y^{2} - 4 x - 21 = 0

in the form of the standard circle equation

(x - 2)^{2} + (y - 0)^{2} = 5^{2}

Therefore the circle properties are:

(a, b) = (2, 0), r = 5

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

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

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

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

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

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

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

(x+1)^2+(y-2)^2=40

(x + 1)^{2} + (y - 2)^{2} = 40
