Für

x^{2} = f (a)

sind die Lösungen

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

b = \frac{25}{169}, b = - \frac{25}{169}

\frac{25}{169} = \frac{5}{13}

- \frac{25}{169} = - \frac{5}{13}

b = \frac{5}{13}, b = - \frac{5}{13}

0.1 x^{2} + 100 x + 8 = 1000

(x + 9) (x + 4) = - 26

9 y^{2} - y + 8 = 0

5 u^{2} - 19 u - 4 = 0

- 5 x^{2} + 7 x - 1 = 0
