foki x^2+10x-2y+21=0

Lösung

foki

x^{2} + 10 x - 2 y + 21 = 0

Lösung

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

Schritte zur Lösung

Rewrite

x^{2} + 10 x - 2 y + 21 = 0

in the standard form

4 \cdot \frac{1}{2} (y - (- 2)) = (x - (- 5))^{2}

(h, k) = (- 5, - 2), p = \frac{1}{2}

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

p

from the center

(- 5, - 2)

along the y-axis

(- 5, - 2 + p)

= (- 5, - 2 + \frac{1}{2})
