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

Lösung

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

Lösung

(a, b) = (- 1, 2), r = 3

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (- 1, 2), r = 3

9x^2+9y^2+54x-36y=-17

9 x^{2} + 9 y^{2} + 54 x - 36 y = - 17

x^{2} + (y + 6)^{2} = 8

x^2+y^2=8(x+y)+4

x^{2} + y^{2} = 8 (x + y) + 4
