x^3-3x^2-8x+24=0

Lösung

x^{3} - 3 x^{2} - 8 x + 24 = 0

Lösung

x = 3, x = - 22, x = 22

+1

Dezimale

x = 3, x = - 2.82842 \dots, x = 2.82842 \dots

Schritte zur Lösung

x^{3} - 3 x^{2} - 8 x + 24 = 0

Faktorisiere

x^{3} - 3 x^{2} - 8 x + 24 : (x - 3) (x + 22) (x - 22)

(x - 3) (x + 22) (x - 22) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x - 3 = 0 or x + 22 = 0 or x - 22 = 0

Löse

x - 3 = 0 : x = 3

Löse

x + 22 = 0 : x = - 22

Löse

x - 22 = 0 : x = 22

Die Lösungen sind

x = 3, x = - 22, x = 22
