(x - 3) 2 x^{3} - 3 x^{2} - 5 x - 12

x 2 x^{3} - 3 x^{2} - 5 x - 12 - 3 2 x^{3} - 3 x^{2} - 5 x - 12

Schritte zur Lösung

(x - 3) 2 x^{3} - 3 x^{2} - 5 x - 12

= 2 x^{3} - 3 x^{2} - 5 x - 12 (x - 3)

Wende das Distributivgesetz an:

a (b - c) = ab - a c

2 x^{3} - 3 x^{2} - 5 x - 12 (x - 3) = 2 x^{3} - 3 x^{2} - 5 x - 12 x - 2 x^{3} - 3 x^{2} - 5 x - 12 \cdot 3

= 2 x^{3} - 3 x^{2} - 5 x - 12 x - 2 x^{3} - 3 x^{2} - 5 x - 12 \cdot 3

= x 2 x^{3} - 3 x^{2} - 5 x - 12 - 3 2 x^{3} - 3 x^{2} - 5 x - 12
