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

Lösung

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

Lösung

x = 0, x = - 1 + 2, x = - 1 - 2

+1

Dezimale

x = 0, x = 0.41421 \dots, x = - 2.41421 \dots

Schritte zur Lösung

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

Faktorisiere

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

x (x^{2} + 2 x - 1) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

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

Löse

x^{2} + 2 x - 1 = 0 : x = - 1 + 2, x = - 1 - 2

Die Lösungen sind

x = 0, x = - 1 + 2, x = - 1 - 2
