x^2+10x-2y+21=0

Lösung

x^{2} + 10 x - 2 y + 21 = 0

(h, k) = (- 5, - 2), p = \frac{1}{2}

Schritte zur Lösung

x^{2} + 10 x - 2 y + 21 = 0

Rewrite

x^{2} + 10 x - 2 y + 21 = 0

in the standard form

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

Therefore parabola properties are:

(h, k) = (- 5, - 2), p = \frac{1}{2}

x = \frac{5}{2} y^{2} - 3

y^{2} < x

x^{2} = 7 y

x^{2} - 8 y - 4 = 0

x + y^{2} + 14 x - 14 y + 73 = 0
