(2x-1)(x^2-14)=0

Lösung

(2 x - 1) (x^{2} - 14) = 0

Lösung

x = \frac{1}{2}, x = - 14, x = 14

+1

Dezimale

x = 0.5, x = - 3.74165 \dots, x = 3.74165 \dots

Schritte zur Lösung

(2 x - 1) (x^{2} - 14) = 0

Faktorisiere

(2 x - 1) (x^{2} - 14) : (2 x - 1) (x + 14) (x - 14)

(2 x - 1) (x + 14) (x - 14) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

2 x - 1 = 0 or x + 14 = 0 or x - 14 = 0

Löse

2 x - 1 = 0 : x = \frac{1}{2}

Löse

x + 14 = 0 : x = - 14

Löse

x - 14 = 0 : x = 14

Die Lösungen sind

x = \frac{1}{2}, x = - 14, x = 14
