π

x^{2} = \frac{500}{π}

Für

x^{2} = f (a)

sind die Lösungen

x = f (a), - f (a)

x = \frac{500}{π}, x = - \frac{500}{π}

\frac{500}{π} = \frac{10 5}{π}

- \frac{500}{π} = - \frac{10 5}{π}

x = \frac{10 5}{π}, x = - \frac{10 5}{π}

a^{2} = \frac{1}{9}

2 x^{2} - 3 x - (6 - 4 x) = 0

x^{2} - 14 x + 130 = 0

2 x^{2} + 9 x = x - 14

(x^{2} + x + 10) = 3
