10d^3+d^2-7d+2=0

Lösung

10 d^{3} + d^{2} - 7 d + 2 = 0

Lösung

d = - 1, d = \frac{2}{5}, d = \frac{1}{2}

+1

Dezimale

d = - 1, d = 0.4, d = 0.5

Schritte zur Lösung

10 d^{3} + d^{2} - 7 d + 2 = 0

Faktorisiere

10 d^{3} + d^{2} - 7 d + 2 : (d + 1) (5 d - 2) (2 d - 1)

(d + 1) (5 d - 2) (2 d - 1) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

d + 1 = 0 or 5 d - 2 = 0 or 2 d - 1 = 0

Löse

d + 1 = 0 : d = - 1

Löse

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

Löse

2 d - 1 = 0 : d = \frac{1}{2}

Die Lösungen sind

d = - 1, d = \frac{2}{5}, d = \frac{1}{2}
