2m^5-7m^4+12m^3+8m^2=0

Lösung

2 m^{5} - 7 m^{4} + 12 m^{3} + 8 m^{2} = 0

Lösung

m = 0, m = - \frac{1}{2}, m = 2 + 2 i, m = 2 - 2 i

Schritte zur Lösung

2 m^{5} - 7 m^{4} + 12 m^{3} + 8 m^{2} = 0

Faktorisiere

2 m^{5} - 7 m^{4} + 12 m^{3} + 8 m^{2} : m^{2} (2 m + 1) (m^{2} - 4 m + 8)

m^{2} (2 m + 1) (m^{2} - 4 m + 8) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

m = 0 or 2 m + 1 = 0 or m^{2} - 4 m + 8 = 0

Löse

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

Löse

m^{2} - 4 m + 8 = 0 : m = 2 + 2 i, m = 2 - 2 i

Die Lösungen sind

m = 0, m = - \frac{1}{2}, m = 2 + 2 i, m = 2 - 2 i
