32 (2 n + 1) (n + 1) : 64 n^{2} + 96 n + 32

= \frac{64 n ^{2} + 96 n + 32}{3 n ^{2}}

Wende Bruchregel an:

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

\frac{64 n ^{2} + 96 n + 32}{3 n ^{2}} = \frac{64 n ^{2}}{3 n ^{2}} + \frac{96 n}{3 n ^{2}} + \frac{32}{3 n ^{2}}

= \frac{64 n ^{2}}{3 n ^{2}} + \frac{96 n}{3 n ^{2}} + \frac{32}{3 n ^{2}}
