x^2+4x+y^2+10y=-20

Lösung

x^{2} + 4 x + y^{2} + 10 y = - 20

Lösung

(a, b) = (- 2, - 5), r = 3

Schritte zur Lösung

x^{2} + 4 x + y^{2} + 10 y = - 20

Rewrite

x^{2} + 4 x + y^{2} + 10 y = - 20

in the form of the standard circle equation

(x - (- 2))^{2} + (y - (- 5))^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (- 2, - 5), r = 3
