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

Lösung

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

Lösung

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

Schritte zur Lösung

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

Rewrite

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

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

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

(x-2)^2+(y-1)^2=25

(x - 2)^{2} + (y - 1)^{2} = 25

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

x^2+y^2-4x+6y+9=0

x^{2} + y^{2} - 4 x + 6 y + 9 = 0

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

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