x^2+7x-k(x)=0

Lösung

x^{2} + 7 x - k (x) = 0

(h, k) = (- \frac{7}{2}, - \frac{49}{4}), p = \frac{1}{4}

Schritte zur Lösung

x^{2} + 7 x - y = 0

Rewrite

x^{2} + 7 x - y = 0

in the standard form

4 \cdot \frac{1}{4} (y - (- \frac{49}{4})) = (x - (- \frac{7}{2}))^{2}

Therefore parabola properties are:

(h, k) = (- \frac{7}{2}, - \frac{49}{4}), p = \frac{1}{4}

2 x + y^{2} = 3

y^{2} + 24 y - 9 x + 255 = 0

x = - (y - 3)^{2} - 4

x = y^{2} - 3 y + 2

(y + 5)^{2} = - 2 (x - 7)
