2x^5+5x^4-3x^2=0

Lösung

2 x^{5} + 5 x^{4} - 3 x^{2} = 0

Lösung

x = 0, x = - 1, x = \frac{- 3 + 33}{4}, x = \frac{- 3 - 33}{4}

+1

Dezimale

x = 0, x = - 1, x = 0.68614 \dots, x = - 2.18614 \dots

Schritte zur Lösung

2 x^{5} + 5 x^{4} - 3 x^{2} = 0

Faktorisiere

2 x^{5} + 5 x^{4} - 3 x^{2} : x^{2} (x + 1) (2 x^{2} + 3 x - 3)

x^{2} (x + 1) (2 x^{2} + 3 x - 3) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x = 0 or x + 1 = 0 or 2 x^{2} + 3 x - 3 = 0

Löse

x + 1 = 0 : x = - 1

Löse

2 x^{2} + 3 x - 3 = 0 : x = \frac{- 3 + 33}{4}, x = \frac{- 3 - 33}{4}

Die Lösungen sind

x = 0, x = - 1, x = \frac{- 3 + 33}{4}, x = \frac{- 3 - 33}{4}
