\frac{- 27 x ^{2}}{- 27} = \frac{1}{- 27}

x^{2} = - \frac{1}{27}

Für

x^{2} = f (a)

sind die Lösungen

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

x = - \frac{1}{27}, x = - - \frac{1}{27}

- \frac{1}{27} = \frac{1}{3 3} i

- - \frac{1}{27} = - \frac{1}{3 3} i

x = \frac{1}{3 3} i, x = - \frac{1}{3 3} i

2 x^{2} - x - 17 = - 5

7 x^{2} - 2 x - 7 = 0

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

x^{2} - 2 a x = b

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