2x^3+7x^2+7x+2=0

Lösung

2 x^{3} + 7 x^{2} + 7 x + 2 = 0

Lösung

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

+1

Dezimale

x = - 1, x = - 0.5, x = - 2

Schritte zur Lösung

2 x^{3} + 7 x^{2} + 7 x + 2 = 0

Faktorisiere

2 x^{3} + 7 x^{2} + 7 x + 2 : (x + 1) (2 x + 1) (x + 2)

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

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x + 1 = 0 or 2 x + 1 = 0 or x + 2 = 0

Löse

x + 1 = 0 : x = - 1

Löse

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

Löse

x + 2 = 0 : x = - 2

Die Lösungen sind

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