foki y^2+2y-4x+9=0

Lösung

foki

y^{2} + 2 y - 4 x + 9 = 0

Lösung

(3, - 1)

Schritte zur Lösung

Rewrite

y^{2} + 2 y - 4 x + 9 = 0

in the standard form

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

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

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

p

from the center

(2, - 1)

along the x-axis

(2 + p, - 1)

= (2 + 1, - 1)
