Beliebt Geometry >

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

Lösung

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

Lösung

(a, b) = (4, - 2), r = 25

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (4, - 2), r = 25

(x+4)^2+(y-4 1/2)^2=42 1/4

(x + 4)^{2} + (y - 4 \frac{1}{2})^{2} = 42 \frac{1}{4}

x^{2} + y^{2} - 6 y + 8 = 0

x^2+y^2-10x-14y+58=0

x^{2} + y^{2} - 10 x - 14 y + 58 = 0

4x^2+4y^2-48x+20y=-141

4 x^{2} + 4 y^{2} - 48 x + 20 y = - 141

x^{2} + (y + 5)^{2} = 9
