leitkurve y^2+6y+2x+1=0

Lösung

leitkurve

y^{2} + 6 y + 2 x + 1 = 0

Lösung

x = \frac{9}{2}

Schritte zur Lösung

Rewrite

y^{2} + 6 y + 2 x + 1 = 0

in the standard form

4 (- \frac{1}{2}) (x - 4) = (y - (- 3))^{2}

(h, k) = (4, - 3), p = - \frac{1}{2}

Parabola is symmetric around the x-axis and so the directrix is a line parallel to the y-axis, a distance

- p

from the center

(4, - 3)

x-coordinate

x = 4 - p

x = 4 - (- \frac{1}{2})

Fasse zusammen

x = \frac{9}{2}
