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

Lösung

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

(h, k) = (- 4, - \frac{6}{5}), p = \frac{5}{2}

Schritte zur Lösung

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

Rewrite

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

in the standard form

4 \cdot \frac{5}{2} (y - (- \frac{6}{5})) = (x - (- 4))^{2}

Therefore parabola properties are:

(h, k) = (- 4, - \frac{6}{5}), p = \frac{5}{2}

y < x^{2}

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

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

2 (y + 2) = (x + 2)^{2}

9 x + 16 y^{2} = 7
