Lösung

erweitern

\frac{( x + 1 ) ( x - 3 )}{2}

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

Schritte zur Lösung

\frac{( x + 1 ) ( x - 3 )}{2}

(x + 1) (x - 3) : x^{2} - 2 x - 3

= \frac{x ^{2} - 2 x - 3}{2}

Wende Bruchregel an:

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

\frac{x ^{2} - 2 x - 3}{2} = \frac{x ^{2}}{2} - \frac{2 x}{2} - \frac{3}{2}

= \frac{x ^{2}}{2} - \frac{2 x}{2} - \frac{3}{2}
