a^{2} = 19.8

Für

x^{2} = f (a)

sind die Lösungen

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

a = 19.8, a = - 19.8

19.8 = \frac{3 11}{5}

- 19.8 = - \frac{3 11}{5}

a = \frac{3 11}{5}, a = - \frac{3 11}{5}

6 t^{2} + 36 = 0

4 s^{2} - 20 s + 25 = 0

f a c t or 3 x^{2} - 8 x - 3 = 0

1 6^{2} = x^{2} + 8^{2}

x^{2} = 8 - x
