4 t (- 3 t^{5} + 5 t^{4}) + 15 (t^{4} - t^{2}) : - 12 t^{6} + 20 t^{5} + 15 t^{4} - 15 t^{2}

= \frac{- 12 t ^{6} + 20 t ^{5} + 15 t ^{4} - 15 t ^{2}}{30}

Wende Bruchregel an:

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

\frac{- 12 t ^{6} + 20 t ^{5} + 15 t ^{4} - 15 t ^{2}}{30} = - \frac{12 t ^{6}}{30} + \frac{20 t ^{5}}{30} + \frac{15 t ^{4}}{30} - \frac{15 t ^{2}}{30}

= - \frac{12 t ^{6}}{30} + \frac{20 t ^{5}}{30} + \frac{15 t ^{4}}{30} - \frac{15 t ^{2}}{30}

\frac{12 t ^{6}}{30} = \frac{2 t ^{6}}{5}

\frac{20 t ^{5}}{30} = \frac{2 t ^{5}}{3}

\frac{15 t ^{4}}{30} = \frac{t ^{4}}{2}

\frac{15 t ^{2}}{30} = \frac{t ^{2}}{2}

= - \frac{2 t ^{6}}{5} + \frac{2 t ^{5}}{3} + \frac{t ^{4}}{2} - \frac{t ^{2}}{2}
