7x^2+9x+k(x)=0

Lösung

7 x^{2} + 9 x + k (x) = 0

Lösung

(h, k) = (- \frac{9}{14}, \frac{81}{28}), p = - \frac{1}{28}

Schritte zur Lösung

7 x^{2} + 9 x + y = 0

Rewrite

7 x^{2} + 9 x + y = 0

in the standard form

4 (- \frac{1}{28}) (y - \frac{81}{28}) = (x - (- \frac{9}{14}))^{2}

Therefore parabola properties are:

(h, k) = (- \frac{9}{14}, \frac{81}{28}), p = - \frac{1}{28}
