leitkurve y^2+4x-8y+12=0

Lösung

leitkurve

y^{2} + 4 x - 8 y + 12 = 0

Lösung

x = 2

Schritte zur Lösung

Rewrite

y^{2} + 4 x - 8 y + 12 = 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 = 2
