x^2-x+y^2+9y+11=0

Lösung

x^{2} - x + y^{2} + 9 y + 11 = 0

Lösung

(a, b) = (\frac{1}{2}, - \frac{9}{2}), r = \frac{19}{2}

Schritte zur Lösung

x^{2} - x + y^{2} + 9 y + 11 = 0

Rewrite

x^{2} - x + y^{2} + 9 y + 11 = 0

in the form of the standard circle equation

(x - \frac{1}{2})^{2} + (y - (- \frac{9}{2}))^{2} = (\frac{19}{2})^{2}

Therefore the circle properties are:

(a, b) = (\frac{1}{2}, - \frac{9}{2}), r = \frac{19}{2}
