(30-4x)(20-2x)(x)=0

Lösung

(30 - 4 x) (20 - 2 x) (x) = 0

Lösung

x = \frac{15}{2}, x = 10, x = 0

+1

Dezimale

x = 7.5, x = 10, x = 0

Schritte zur Lösung

(30 - 4 x) (20 - 2 x) (x) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

30 - 4 x = 0 or 20 - 2 x = 0 or x = 0

Löse

30 - 4 x = 0 : x = \frac{15}{2}

Löse

20 - 2 x = 0 : x = 10

Die Lösungen sind

x = \frac{15}{2}, x = 10, x = 0
