leitkurve y^2-4y-4x=0

Lösung

leitkurve

y^{2} - 4 y - 4 x = 0

Lösung

x = - 2

Schritte zur Lösung

Rewrite

y^{2} - 4 y - 4 x = 0

in the standard form

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

(h, k) = (- 1, 2), 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, 2)

x-coordinate

x = - 1 - p

x = - 1 - 1

Fasse zusammen

x = - 2
