foki x^2+8x-5

Lösung

foki

x^{2} + 8 x - 5

Lösung

(- 4, - \frac{83}{4})

Schritte zur Lösung

Rewrite

y = x^{2} + 8 x - 5

in the standard form

4 \cdot \frac{1}{4} (y - (- 21)) = (x - (- 4))^{2}

(h, k) = (- 4, - 21), p = \frac{1}{4}

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

p

from the center

(- 4, - 21)

along the y-axis

(- 4, - 21 + p)

= (- 4, - 21 + \frac{1}{4})

Fasse zusammen
