(x-1)(x^2-13)=0

Lösung

(x - 1) (x^{2} - 13) = 0

Lösung

x = 1, x = - 13, x = 13

+1

Dezimale

x = 1, x = - 3.60555 \dots, x = 3.60555 \dots

Schritte zur Lösung

(x - 1) (x^{2} - 13) = 0

Faktorisiere

(x - 1) (x^{2} - 13) : (x - 1) (x + 13) (x - 13)

(x - 1) (x + 13) (x - 13) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x - 1 = 0 or x + 13 = 0 or x - 13 = 0

Löse

x - 1 = 0 : x = 1

Löse

x + 13 = 0 : x = - 13

Löse

x - 13 = 0 : x = 13

Die Lösungen sind

x = 1, x = - 13, x = 13
