x^{2} = \frac{1}{2}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{1}{2}, x = - \frac{1}{2}

\frac{1}{2} = \frac{1}{2}

- \frac{1}{2} = - \frac{1}{2}

x = \frac{1}{2}, x = - \frac{1}{2}

y^{2} = 8 (\frac{y}{2})

so l v e f or y, y x^{2} + 2 y = 5 x

so l v e f or y, y^{2} = x^{2} + 6 x + 9

9 p^{2} + 17 p + 12 = 3 p^{2}

4 x^{2} - 5 x = - 1
