7x^2+5x-k(x)=0

Lösung

7 x^{2} + 5 x - k (x) = 0

Lösung

(h, k) = (- \frac{5}{14}, - \frac{25}{28}), p = \frac{1}{28}

Schritte zur Lösung

7 x^{2} + 5 x - y = 0

Rewrite

7 x^{2} + 5 x - y = 0

in the standard form

4 \cdot \frac{1}{28} (y - (- \frac{25}{28})) = (x - (- \frac{5}{14}))^{2}

Therefore parabola properties are:

(h, k) = (- \frac{5}{14}, - \frac{25}{28}), p = \frac{1}{28}

x^2-16y-4x-12=0

x^{2} - 16 y - 4 x - 12 = 0

(x-5)^2=-29(y-1)

(x - 5)^{2} = - 29 (y - 1)

solvefor x, 9/(u(x)^3)= x/(5u(x)^5)

so l v e f or x, \frac{9}{u ( x ) ^{3}} = \frac{x}{5 u ( x ) ^{5}}
