(x+2)^3=1

Lösung

(x + 2)^{3} = 1

x = - 1, x = - \frac{5}{2} + i \frac{3}{2}, x = - \frac{5}{2} - i \frac{3}{2}

Schritte zur Lösung

(x + 2)^{3} = 1

Für

g^{3} (x) = f (a)

sind die Lösungen

g (x) = 3 f (a), 3 f (a) \frac{- 1 - 3 i}{2}, 3 f (a) \frac{- 1 + 3 i}{2}

Löse

x + 2 = 1 : x = - 1

Löse

x + 2 = \frac{- 1 + 3 i}{2} : x = - \frac{5}{2} + i \frac{3}{2}

Löse

x + 2 = \frac{- 1 - 3 i}{2} : x = - \frac{5}{2} - i \frac{3}{2}

Die Lösungen sind

x = - 1, x = - \frac{5}{2} + i \frac{3}{2}, x = - \frac{5}{2} - i \frac{3}{2}
