c (- 2 b d + 2 b c + d^{2} - c^{2}) : - 2 c b d + 2 c^{2} b + c d^{2} - c^{3}

= \frac{- 2 c b d + 2 c ^{2} b + c d ^{2} - c ^{3}}{2 d}

Wende Bruchregel an:

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

\frac{- 2 c b d + 2 c ^{2} b + c d ^{2} - c ^{3}}{2 d} = - \frac{2 c b d}{2 d} + \frac{2 c ^{2} b}{2 d} + \frac{c d ^{2}}{2 d} - \frac{c ^{3}}{2 d}

= - \frac{2 c b d}{2 d} + \frac{2 c ^{2} b}{2 d} + \frac{c d ^{2}}{2 d} - \frac{c ^{3}}{2 d}
