Beliebt Geometry >

x^2+y^2+4x+8y+16=0

Lösung

x^{2} + y^{2} + 4 x + 8 y + 16 = 0

Lösung

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

Schritte zur Lösung

x^{2} + y^{2} + 4 x + 8 y + 16 = 0

Rewrite

x^{2} + y^{2} + 4 x + 8 y + 16 = 0

in the form of the standard circle equation

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

Therefore the circle properties are:

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

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

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

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

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

(x-1)^2+(y-1)^2=25

(x - 1)^{2} + (y - 1)^{2} = 25

x^2+y^2-10x-6y-30=0

x^{2} + y^{2} - 10 x - 6 y - 30 = 0
