leitkurve x^2-4x-5y+7=0

Lösung

leitkurve

x^{2} - 4 x - 5 y + 7 = 0

Lösung

y = - \frac{13}{20}

Schritte zur Lösung

Rewrite

x^{2} - 4 x - 5 y + 7 = 0

in the standard form

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

(h, k) = (2, \frac{3}{5}), p = \frac{5}{4}

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

- p

from the center

(2, \frac{3}{5})

y-coordinate

y = \frac{3}{5} - p

y = \frac{3}{5} - \frac{5}{4}

Fasse zusammen

y = - \frac{13}{20}
