leitkurve 4x^2+48y+12x=159

Lösung

leitkurve

4 x^{2} + 48 y + 12 x = 159

Lösung

y = \frac{13}{2}

Schritte zur Lösung

Rewrite

4 x^{2} + 48 y + 12 x = 159

in the standard form

4 (- 3) (y - \frac{7}{2}) = (x - (- \frac{3}{2}))^{2}

(h, k) = (- \frac{3}{2}, \frac{7}{2}), p = - 3

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

(- \frac{3}{2}, \frac{7}{2})

y-coordinate

y = \frac{7}{2} - p

y = \frac{7}{2} - (- 3)

Fasse zusammen

y = \frac{13}{2}
