25

x^{2} = \frac{9}{25}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{9}{25}, x = - \frac{9}{25}

\frac{9}{25} = \frac{3}{5}

- \frac{9}{25} = - \frac{3}{5}

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

4 x^{2} - 12 x + 9 = 9

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

x^{2} + 2 x + 1 = 15

(x - 5) (x + 3) = 9

14 x^{2} - 72 x + 64 = 0
