9x^2+9y^2+18x-18y+14=0

Lösung

9 x^{2} + 9 y^{2} + 18 x - 18 y + 14 = 0

Lösung

(a, b) = (- 1, 1), r = \frac{2}{3}

Schritte zur Lösung

9 x^{2} + 9 y^{2} + 18 x - 18 y + 14 = 0

Rewrite

9 x^{2} + 9 y^{2} + 18 x - 18 y + 14 = 0

in the form of the standard circle equation

(x - (- 1))^{2} + (y - 1)^{2} = (\frac{2}{3})^{2}

Therefore the circle properties are:

(a, b) = (- 1, 1), r = \frac{2}{3}
