foki (x+sqrt(2))(x-sqrt(2))

Lösung

foki

(x + 2) (x - 2)

Lösung

(0, - \frac{7}{4})

Schritte zur Lösung

Rewrite

y = (x + 2) (x - 2)

in the standard form

4 \cdot \frac{1}{4} (y - (- 2)) = (x - 0)^{2}

(h, k) = (0, - 2), p = \frac{1}{4}

Parabola is symmetric around the y-axis and so the focus lies a distance

p

from the center

(0, - 2)

along the y-axis

(0, - 2 + p)

= (0, - 2 + \frac{1}{4})

Fasse zusammen

(0, - \frac{7}{4})
