x-2x^3=0

Lösung

x - 2 x^{3} = 0

Lösung

x = 0, x = - \frac{1}{2}, x = \frac{1}{2}

+1

Dezimale

x = 0, x = - 0.70710 \dots, x = 0.70710 \dots

Schritte zur Lösung

x - 2 x^{3} = 0

Faktorisiere

x - 2 x^{3} : - x (2 x + 1) (2 x - 1)

- x (2 x + 1) (2 x - 1) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x = 0 or 2 x + 1 = 0 or 2 x - 1 = 0

Löse

2 x + 1 = 0 : x = - \frac{1}{2}

Löse

2 x - 1 = 0 : x = \frac{1}{2}

Die Lösungen sind

x = 0, x = - \frac{1}{2}, x = \frac{1}{2}
