64

x^{2} = \frac{49}{64}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{49}{64}, x = - \frac{49}{64}

\frac{49}{64} = \frac{7}{8}

- \frac{49}{64} = - \frac{7}{8}

x = \frac{7}{8}, x = - \frac{7}{8}

36 - 85 x + 9 x^{2} = 0

m + 4 = \frac{13}{2}

2 x^{2} - 9 x - 26 = 0

\frac{( 25 + 4 )}{3} + 25 = 20

(x + 8)^{2} = 2 x + 15
