Beliebt Geometry >

(x^2+4x)+(y^2+4y)=9

Lösung

(x^{2} + 4 x) + (y^{2} + 4 y) = 9

Lösung

(a, b) = (- 2, - 2), r = 17

Schritte zur Lösung

x^{2} + 4 x + (y^{2} + 4 y) = 9

Rewrite

x^{2} + 4 x + (y^{2} + 4 y) = 9

in the form of the standard circle equation

(x - (- 2))^{2} + (y - (- 2))^{2} = (17)^{2}

Therefore the circle properties are:

(a, b) = (- 2, - 2), r = 17

(x-3)^2+(y+2)^2=17

(x - 3)^{2} + (y + 2)^{2} = 17

x^2+y^2-16x+8y+64=0

x^{2} + y^{2} - 16 x + 8 y + 64 = 0

4x^2+4y^2-6x+10y= 1/2

4 x^{2} + 4 y^{2} - 6 x + 10 y = \frac{1}{2}

(x+15)^2+(y-12)^2=64

(x + 15)^{2} + (y - 12)^{2} = 64

(x-2)^2+(y+4)^2=36

(x - 2)^{2} + (y + 4)^{2} = 36
