x = - 2.33333 \dots, x = - 3.31662 \dots, x = 3.31662 \dots

Schritte zur Lösung

3 x^{3} + 7 x^{2} - 33 x - 77 = 0

Faktorisiere

3 x^{3} + 7 x^{2} - 33 x - 77 : (3 x + 7) (x + 11) (x - 11)

(3 x + 7) (x + 11) (x - 11) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

3 x + 7 = 0 or x + 11 = 0 or x - 11 = 0

Löse

3 x + 7 = 0 : x = - \frac{7}{3}

Löse

x + 11 = 0 : x = - 11

Löse

x - 11 = 0 : x = 11

Die Lösungen sind

x = - \frac{7}{3}, x = - 11, x = 11
