Beliebt Geometry >

x^2+x+y^2+2y=0

Lösung

x^{2} + x + y^{2} + 2 y = 0

Lösung

(a, b) = (- \frac{1}{2}, - 1), r = \frac{5}{2}

Schritte zur Lösung

x^{2} + x + y^{2} + 2 y = 0

Rewrite

x^{2} + x + y^{2} + 2 y = 0

in the form of the standard circle equation

(x - (- \frac{1}{2}))^{2} + (y - (- 1))^{2} = (\frac{5}{2})^{2}

Therefore the circle properties are:

(a, b) = (- \frac{1}{2}, - 1), r = \frac{5}{2}
