5

x^{2} = \frac{12}{5}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{12}{5}, x = - \frac{12}{5}

\frac{12}{5} = \frac{2 3}{5}

- \frac{12}{5} = - \frac{2 3}{5}

x = \frac{2 3}{5}, x = - \frac{2 3}{5}

- 15 x^{2} - 7 x + 2 = 0

3 (x - 3) (x + 4) = 0

so l v e f or x, y = x^{2} - 7

0.5 x^{2} - x - 0.5 = 0

3 m^{2} + 16 m + 13 = 0
