2x^3-x^2-x=0

Lösung

2 x^{3} - x^{2} - x = 0

Lösung

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

+1

Dezimale

x = 0, x = - 0.5, x = 1

Schritte zur Lösung

2 x^{3} - x^{2} - x = 0

Faktorisiere

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

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

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

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

Löse

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

Löse

x - 1 = 0 : x = 1

Die Lösungen sind

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