faktorisieren x^4+x^3-6x^2-4x+8

Lösung

faktorisieren

x^{4} + x^{3} - 6 x^{2} - 4 x + 8

Lösung

(x - 1) (x + 2)^{2} (x - 2)

Schritte zur Lösung

x^{4} + x^{3} - 6 x^{2} - 4 x + 8

Wende den rationalen Nullstellentest an

= (x - 1) \frac{x ^{4} + x ^{3} - 6 x ^{2} - 4 x + 8}{x - 1}

\frac{x ^{4} + x ^{3} - 6 x ^{2} - 4 x + 8}{x - 1} = x^{3} + 2 x^{2} - 4 x - 8

= (x - 1) (x^{3} + 2 x^{2} - 4 x - 8)

Faktorisiere

x^{3} + 2 x^{2} - 4 x - 8 : (x + 2) (x + 2) (x - 2)

= (x - 1) (x + 2) (x + 2) (x - 2)

Wende Exponentenregel an:

aa = a^{2}

(x + 2) (x + 2) = (x + 2)^{2}

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