Beliebt Geometry >

72=x^2+6x+9+y^2-4y+4

Lösung

72 = x^{2} + 6 x + 9 + y^{2} - 4 y + 4

Lösung

(a, b) = (- 3, 2), r = 62

Schritte zur Lösung

72 = x^{2} + 6 x + 9 + y^{2} - 4 y + 4

Rewrite

72 = x^{2} + 6 x + 9 + y^{2} - 4 y + 4

in the form of the standard circle equation

(x - (- 3))^{2} + (y - 2)^{2} = (62)^{2}

Therefore the circle properties are:

(a, b) = (- 3, 2), r = 62

(x+6)^2+(y-4)^2=16

(x + 6)^{2} + (y - 4)^{2} = 16

x^2+y^2-14x+31=0

x^{2} + y^{2} - 14 x + 31 = 0

(x-8)^2+(y-4)^2=25

(x - 8)^{2} + (y - 4)^{2} = 25

x^2+y^2-4x+10y-13=0

x^{2} + y^{2} - 4 x + 10 y - 13 = 0

3 x^{2} + 3 y^{2} = 30
