3s^3-5s+2=0

Lösung

3 s^{3} - 5 s + 2 = 0

Lösung

s = 1, s = \frac{- 3 + 33}{6}, s = \frac{- 3 - 33}{6}

+1

Dezimale

s = 1, s = 0.45742 \dots, s = - 1.45742 \dots

Schritte zur Lösung

3 s^{3} - 5 s + 2 = 0

Faktorisiere

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

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

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

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

Löse

s - 1 = 0 : s = 1

Löse

3 s^{2} + 3 s - 2 = 0 : s = \frac{- 3 + 33}{6}, s = \frac{- 3 - 33}{6}

Die Lösungen sind

s = 1, s = \frac{- 3 + 33}{6}, s = \frac{- 3 - 33}{6}
