(x-3)^4-8(x-3)^2-9=0

Lösung

(x - 3)^{4} - 8 (x - 3)^{2} - 9 = 0

Lösung

x = 0, x = 6, x = 3 + i, x = 3 - i

Schritte zur Lösung

(x - 3)^{4} - 8 (x - 3)^{2} - 9 = 0

Schreibe

(x - 3)^{4} - 8 (x - 3)^{2} - 9

um:

x^{4} - 12 x^{3} + 46 x^{2} - 60 x

x^{4} - 12 x^{3} + 46 x^{2} - 60 x = 0

Faktorisiere

x^{4} - 12 x^{3} + 46 x^{2} - 60 x : x (x - 6) (x^{2} - 6 x + 10)

x (x - 6) (x^{2} - 6 x + 10) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x = 0 or x - 6 = 0 or x^{2} - 6 x + 10 = 0

Löse

x - 6 = 0 : x = 6

Löse

x^{2} - 6 x + 10 = 0 : x = 3 + i, x = 3 - i

Die Lösungen sind

x = 0, x = 6, x = 3 + i, x = 3 - i
