9x^2+9y^2+42x+84y=-65

Lösung

9 x^{2} + 9 y^{2} + 42 x + 84 y = - 65

Lösung

(a, b) = (- \frac{7}{3}, - \frac{14}{3}), r = 25

Schritte zur Lösung

9 x^{2} + 9 y^{2} + 42 x + 84 y = - 65

Rewrite

9 x^{2} + 9 y^{2} + 42 x + 84 y = - 65

in the form of the standard circle equation

(x - (- \frac{7}{3}))^{2} + (y - (- \frac{14}{3}))^{2} = (25)^{2}

Therefore the circle properties are:

(a, b) = (- \frac{7}{3}, - \frac{14}{3}), r = 25
