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

= \frac{x ^{3} + 8 x ^{2} + 2 x}{9}

Wende Bruchregel an:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{x ^{3} + 8 x ^{2} + 2 x}{9} = \frac{x ^{3}}{9} + \frac{8 x ^{2}}{9} + \frac{2 x}{9}

= \frac{x ^{3}}{9} + \frac{8 x ^{2}}{9} + \frac{2 x}{9}
