leitkurve 4y^2-48x-20y=71

Lösung

leitkurve

4 y^{2} - 48 x - 20 y = 71

Lösung

x = - 5

Schritte zur Lösung

Rewrite

4 y^{2} - 48 x - 20 y = 71

in the standard form

4 \cdot 3 (x - (- 2)) = (y - \frac{5}{2})^{2}

(h, k) = (- 2, \frac{5}{2}), p = 3

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, \frac{5}{2})

x-coordinate

x = - 2 - p

x = - 2 - 3

Fasse zusammen

x = - 5
