-25x^2+y9^2=225

Lösung

- 25 x^{2} + y 9^{2} = 225

(h, k) = (0, \frac{25}{9}), p = \frac{81}{100}

Schritte zur Lösung

- 25 x^{2} + y \cdot 9^{2} = 225

Rewrite

- 25 x^{2} + y \cdot 9^{2} = 225

in the standard form:

4 \cdot \frac{81}{100} (y - \frac{25}{9}) = (x - 0)^{2}

Therefore parabola properties are:

(h, k) = (0, \frac{25}{9}), p = \frac{81}{100}

y^{1} = (x + 1)^{2}

(x + 3) 2 + (y + 1)^{2} = 36

x = 4 y^{2} - 4

x = y^{2} + 6 y - 4

x = y^{2} + 6 y - 7
