v a l u es (x + 1) (x - 2) (x - 4)

e l v a u s x^{3} - 5 e l v a u s x^{2} + 2 e l v a u s x + 8 e l v a u s

Schritte zur Lösung

v a l u es (x + 1) (x - 2) (x - 4)

= e l v a u s (x + 1) (x - 2) (x - 4)

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

= v a l u es (x^{2} - x - 2) (x - 4)

(x^{2} - x - 2) (x - 4) : x^{3} - 5 x^{2} + 2 x + 8

= v a l u es (x^{3} - 5 x^{2} + 2 x + 8)
