foki x^2-2x-8y-31=0

Lösung

foki

x^{2} - 2 x - 8 y - 31 = 0

Lösung

(1, - 2)

Schritte zur Lösung

Rewrite

x^{2} - 2 x - 8 y - 31 = 0

in the standard form

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

(h, k) = (1, - 4), p = 2

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

p

from the center

(1, - 4)

along the y-axis

(1, - 4 + p)

= (1, - 4 + 2)
