leitkurve y^2+8y+4x+20=0

Lösung

leitkurve

y^{2} + 8 y + 4 x + 20 = 0

Lösung

x = 0

Schritte zur Lösung

Rewrite

y^{2} + 8 y + 4 x + 20 = 0

in the standard form

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

(h, k) = (- 1, - 4), p = - 1

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

(- 1, - 4)

x-coordinate

x = - 1 - p

x = - 1 - (- 1)

Fasse zusammen

x = 0
