5 x (6480 - 5 x^{2}) : 32400 x - 25 x^{3}

= \frac{32400 x - 25 x ^{3}}{14}

Wende Bruchregel an:

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

\frac{32400 x - 25 x ^{3}}{14} = \frac{32400 x}{14} - \frac{25 x ^{3}}{14}

= \frac{32400 x}{14} - \frac{25 x ^{3}}{14}

Streiche

\frac{32400 x}{14} : \frac{16200 x}{7}

= \frac{16200 x}{7} - \frac{25 x ^{3}}{14}

Rewrite in standard form

= - \frac{25 x ^{3}}{14} + \frac{16200 x}{7}
