y^2+8y+20x+56=0

Lösung

y^{2} + 8 y + 20 x + 56 = 0

(h, k) = (- 2, - 4), p = - 5

Schritte zur Lösung

y^{2} + 8 y + 20 x + 56 = 0

Rewrite

y^{2} + 8 y + 20 x + 56 = 0

in the standard form

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

Therefore parabola properties are:

(h, k) = (- 2, - 4), p = - 5

y^{2} + 10 x = 0

x^{2} + 8 x - 10 y = - 4

y < x^{2}

x = \frac{y ^{2}}{4}

y - 17 = 2 x^{2} + 12 x
