x^{2} = \frac{9}{2}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{9}{2}, x = - \frac{9}{2}

\frac{9}{2} = \frac{3}{2}

- \frac{9}{2} = - \frac{3}{2}

x = \frac{3}{2}, x = - \frac{3}{2}

15 \leq - 6 x

36 x^{2} + 25 = 60 x

- 3 x - 6 x = 6 + x - 7 x

- 2 x + 3 \geq 5

4 x + 7 = 23
