Beliebt Geometry >

x^2+y^2-8x+4y=-11

Lösung

x^{2} + y^{2} - 8 x + 4 y = - 11

Lösung

(a, b) = (4, - 2), r = 3

Schritte zur Lösung

x^{2} + y^{2} - 8 x + 4 y = - 11

Rewrite

x^{2} + y^{2} - 8 x + 4 y = - 11

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (4, - 2), r = 3

a^{2} = 8 - 2 b - b^{2}

(x-1)^2+(y-3)^2=9

(x - 1)^{2} + (y - 3)^{2} = 9

(x+3)^2+(y-4)^2=36

(x + 3)^{2} + (y - 4)^{2} = 36

x^{2} + y^{2} = 42

x^{2} + y^{2} = 52
