-x^3+8x^2-13x+2=0

Lösung

- x^{3} + 8 x^{2} - 13 x + 2 = 0

Lösung

x = 2, x = 3 + 22, x = 3 - 22

+1

Dezimale

x = 2, x = 5.82842 \dots, x = 0.17157 \dots

Schritte zur Lösung

- x^{3} + 8 x^{2} - 13 x + 2 = 0

Faktorisiere

- x^{3} + 8 x^{2} - 13 x + 2 : - (x - 2) (x^{2} - 6 x + 1)

- (x - 2) (x^{2} - 6 x + 1) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x - 2 = 0 or x^{2} - 6 x + 1 = 0

Löse

x - 2 = 0 : x = 2

Löse

x^{2} - 6 x + 1 = 0 : x = 3 + 22, x = 3 - 22

Die Lösungen sind

x = 2, x = 3 + 22, x = 3 - 22
