Lösung

erweitern

\frac{P ( a l - a c ) c}{l ^{2}}

\frac{P a c}{l} - \frac{P a c ^{2}}{l ^{2}}

P (a l - a c) c : lP a c - P a c^{2}

= \frac{lP a c - P a c ^{2}}{l ^{2}}

Wende Bruchregel an:

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

\frac{lP a c - P a c ^{2}}{l ^{2}} = \frac{lP a c}{l ^{2}} - \frac{P a c ^{2}}{l ^{2}}

= \frac{lP a c}{l ^{2}} - \frac{P a c ^{2}}{l ^{2}}

Streiche

\frac{lP a c}{l ^{2}} : \frac{P a c}{l}

= \frac{P a c}{l} - \frac{P a c ^{2}}{l ^{2}}
