2x^2+2y^2+4x-8y-40=0

Lösung

2 x^{2} + 2 y^{2} + 4 x - 8 y - 40 = 0

Lösung

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

Schritte zur Lösung

2 x^{2} + 2 y^{2} + 4 x - 8 y - 40 = 0

Rewrite

2 x^{2} + 2 y^{2} + 4 x - 8 y - 40 = 0

in the form of the standard circle equation

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

Therefore the circle properties are:

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