foki-2x^2-4x+y+70=0

Lösung

foki

- 2 x^{2} - 4 x + y + 70 = 0

Lösung

(- 1, - \frac{575}{8})

Schritte zur Lösung

Rewrite

- 2 x^{2} - 4 x + y + 70 = 0

in the standard form

4 \cdot \frac{1}{8} (y - (- 72)) = (x - (- 1))^{2}

(h, k) = (- 1, - 72), p = \frac{1}{8}

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

p

from the center

(- 1, - 72)

along the y-axis

(- 1, - 72 + p)

= (- 1, - 72 + \frac{1}{8})
