Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{245025}{37}, x = - \frac{245025}{37}

\frac{245025}{37} = \frac{495}{37}

- \frac{245025}{37} = - \frac{495}{37}

x = \frac{495}{37}, x = - \frac{495}{37}

∣ x + 4 ∣ > 9

1 - x > 0

- 100 x (- 25 x^{2} + 9) > 0

- x^{2} - 5 x - 6 = 0
