Lösung

erweitern

\frac{8 ( 2 - 2 x ) ^{3}}{3}

- \frac{64 x ^{3}}{3} + 64 x^{2} - 64 x + \frac{64}{3}

Schritte zur Lösung

\frac{8 ( 2 - 2 x ) ^{3}}{3}

(2 - 2 x)^{3} = 8 - 24 x + 24 x^{2} - 8 x^{3}

= \frac{8 ( - 8 x ^{3} + 24 x ^{2} - 24 x + 8 )}{3}

8 (8 - 24 x + 24 x^{2} - 8 x^{3}) : 64 - 192 x + 192 x^{2} - 64 x^{3}

= \frac{64 - 192 x + 192 x ^{2} - 64 x ^{3}}{3}

Wende Bruchregel an:

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

\frac{64 - 192 x + 192 x ^{2} - 64 x ^{3}}{3} = \frac{64}{3} - \frac{192 x}{3} + \frac{192 x ^{2}}{3} - \frac{64 x ^{3}}{3}

= \frac{64}{3} - \frac{192 x}{3} + \frac{192 x ^{2}}{3} - \frac{64 x ^{3}}{3}
