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

Lösung

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

Lösung

(h, k) = (- \frac{7}{10}, - \frac{49}{20}), p = \frac{1}{20}

Schritte zur Lösung

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

Rewrite

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

in the standard form

4 \cdot \frac{1}{20} (y - (- \frac{49}{20})) = (x - (- \frac{7}{10}))^{2}

Therefore parabola properties are:

(h, k) = (- \frac{7}{10}, - \frac{49}{20}), p = \frac{1}{20}

4x^2-12x+q(x)=0

4 x^{2} - 12 x + q (x) = 0

x = y^{2} - 9 x + 3

(1-x)^2+(2-y)^2-(7-x)^2+y^2=40

(1 - x)^{2} + (2 - y)^{2} - (7 - x)^{2} + y^{2} = 40
