25

x^{2} = \frac{4}{25}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{4}{25}, x = - \frac{4}{25}

\frac{4}{25} = \frac{2}{5}

- \frac{4}{25} = - \frac{2}{5}

x = \frac{2}{5}, x = - \frac{2}{5}

- 2 (x + 4) + 6 = - 3

3 x - 4 > x + 6

\frac{5}{4} + \frac{3 x}{2} = \frac{7 x}{6}

5 x + 3 = 7 x - 1

5 x + 8 \leq 7 x - 12
