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

Lösung

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

Lösung

r = 0, r = 1, r = 2, r = i, r = - i

Schritte zur Lösung

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

Faktorisiere

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

r (r - 1) (r - 2) (r^{2} + 1) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

r = 0 or r - 1 = 0 or r - 2 = 0 or r^{2} + 1 = 0

Löse

r - 1 = 0 : r = 1

Löse

r - 2 = 0 : r = 2

Löse

r^{2} + 1 = 0 : r = i, r = - i

Die Lösungen sind

r = 0, r = 1, r = 2, r = i, r = - i
