4

x^{2} = - 16

Für

x^{2} = f (a)

sind die Lösungen

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

x = - 16, x = - - 16

- 16 = 4 i

- - 16 = - 4 i

x = 4 i, x = - 4 i

x^{2} - 6 x + 7 = 4 x

\frac{5}{4} x^{2} + 7 x + 9 = 0

so l v e f or y, y x^{2} - 4 y - x^{2} = 0

(x + 8) (4 x + 1) = 0

so l v e f or y, x = a - 2 b y^{2}
