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

Lösung

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

Lösung

(a, b) = (4, - 1), r = 3

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

(x - 4)^{2} + (y - (- 1))^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (4, - 1), r = 3

2 x^{2} + 2 y^{2} - 12 x + 2 y + 1 = 0

4x^2+4y^2+20x-8y+9=0

4 x^{2} + 4 y^{2} + 20 x - 8 y + 9 = 0

1/2 y^2=-1/2 x^2+12.5

\frac{1}{2} y^{2} = - \frac{1}{2} x^{2} + 12.5

(x-2)^2+(y+3)^2=11

(x - 2)^{2} + (y + 3)^{2} = 11

x^2+y^2+16x-14y+49=0

x^{2} + y^{2} + 16 x - 14 y + 49 = 0
