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 = 1

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} = 1^{2}

Therefore the circle properties are:

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