2x^2+2y^2-16x+4y+20=0

Lösung

2 x^{2} + 2 y^{2} - 16 x + 4 y + 20 = 0

Lösung

(a, b) = (4, - 1), r = 7

Schritte zur Lösung

2 x^{2} + 2 y^{2} - 16 x + 4 y + 20 = 0

Rewrite

2 x^{2} + 2 y^{2} - 16 x + 4 y + 20 = 0

in the form of the standard circle equation

(x - 4)^{2} + (y - (- 1))^{2} = (7)^{2}

Therefore the circle properties are:

(a, b) = (4, - 1), r = 7
