x^{2} = \frac{25}{16}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{25}{16}, x = - \frac{25}{16}

\frac{25}{16} = \frac{5}{4}

- \frac{25}{16} = - \frac{5}{4}

x = \frac{5}{4}, x = - \frac{5}{4}

7 x^{2} - 2 x + 8 = 0

400 = x^{2}

s^{2} + 25 = 0

3 x^{2} - 41 x + 110 = 0

(2 x + 3) (x - 5) = 0
