(5-2x)*(x^2-9)=0

Lösung

(5 - 2 x) \cdot (x^{2} - 9) = 0

Lösung

x = - 3, x = 3, x = \frac{5}{2}

+1

Dezimale

x = - 3, x = 3, x = 2.5

Schritte zur Lösung

(5 - 2 x) (x^{2} - 9) = 0

Faktorisiere

(5 - 2 x) (x^{2} - 9) : - (x + 3) (x - 3) (2 x - 5)

- (x + 3) (x - 3) (2 x - 5) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x + 3 = 0 or x - 3 = 0 or 2 x - 5 = 0

Löse

x + 3 = 0 : x = - 3

Löse

x - 3 = 0 : x = 3

Löse

2 x - 5 = 0 : x = \frac{5}{2}

Die Lösungen sind

x = - 3, x = 3, x = \frac{5}{2}
