leitkurve 2y^2-16y+72=20x

Lösung

leitkurve

2 y^{2} - 16 y + 72 = 20 x

Lösung

x = - \frac{1}{2}

Schritte zur Lösung

Rewrite

2 y^{2} - 16 y + 72 = 20 x

in the standard form

4 \cdot \frac{5}{2} (x - 2) = (y - 4)^{2}

(h, k) = (2, 4), p = \frac{5}{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

(2, 4)

x-coordinate

x = 2 - p

x = 2 - \frac{5}{2}

Fasse zusammen

x = - \frac{1}{2}
