(3x+2)(x+9)(x-2)=0

Lösung

(3 x + 2) (x + 9) (x - 2) = 0

Lösung

x = - \frac{2}{3}, x = - 9, x = 2

+1

Dezimale

x = - 0.66666 \dots, x = - 9, x = 2

Schritte zur Lösung

(3 x + 2) (x + 9) (x - 2) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

3 x + 2 = 0 or x + 9 = 0 or x - 2 = 0

Löse

3 x + 2 = 0 : x = - \frac{2}{3}

Löse

x + 9 = 0 : x = - 9

Löse

x - 2 = 0 : x = 2

Die Lösungen sind

x = - \frac{2}{3}, x = - 9, x = 2
