8

x^{2} = \frac{135}{8}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{135}{8}, x = - \frac{135}{8}

\frac{135}{8} = \frac{3 15}{2 2}

- \frac{135}{8} = - \frac{3 15}{2 2}

x = \frac{3 15}{2 2}, x = - \frac{3 15}{2 2}

x^{2} + x - 27 = 5 x + 5

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

3 x^{2} - 2 x = x - 1

so l v e f or x, 14 x^{2} + 36 x y - y^{2} - 3 x - 2 y = 0

x^{2} - 41 = - 5
