Beliebt Geometry >

x^2+y^2+2x-8y-13=0

Lösung

x^{2} + y^{2} + 2 x - 8 y - 13 = 0

Lösung

(a, b) = (- 1, 4), r = 30

Schritte zur Lösung

x^{2} + y^{2} + 2 x - 8 y - 13 = 0

Rewrite

x^{2} + y^{2} + 2 x - 8 y - 13 = 0

in the form of the standard circle equation

(x - (- 1))^{2} + (y - 4)^{2} = (30)^{2}

Therefore the circle properties are:

(a, b) = (- 1, 4), r = 30

x^2+6x+y^2-8y=-16

x^{2} + 6 x + y^{2} - 8 y = - 16

40(y-5)^2+40(x+2)^2=2000

40 (y - 5)^{2} + 40 (x + 2)^{2} = 2000

5 x^{2} + 5 y^{2} - 3 x = 0

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

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

(x-4)^2+(y-0)^2=16

(x - 4)^{2} + (y - 0)^{2} = 16
