foki y^2+2y+1=-2x+4

Lösung

foki

y^{2} + 2 y + 1 = - 2 x + 4

Lösung

(\frac{3}{2}, - 1)

Schritte zur Lösung

Rewrite

y^{2} + 2 y + 1 = - 2 x + 4

in the standard form

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

(h, k) = (2, - 1), p = - \frac{1}{2}

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 + (- \frac{1}{2}), - 1)
