9x^2+9y^2-42x+84y+65=0

Lösung

9 x^{2} + 9 y^{2} - 42 x + 84 y + 65 = 0

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 = 0

Rewrite

9 x^{2} + 9 y^{2} - 42 x + 84 y + 65 = 0

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
