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

Lösung

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

Lösung

(a, b) = (- 2, 1), r = 5

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

(x - (- 2))^{2} + (y - 1)^{2} = 5^{2}

Therefore the circle properties are:

(a, b) = (- 2, 1), r = 5
