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

Lösung

foki

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

Lösung

(- 2, 1)

Schritte zur Lösung

Rewrite

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

in the standard form

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

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

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

p

from the center

(- 2, 2)

along the y-axis

(- 2, 2 + p)

= (- 2, 2 + (- 1))
