erweitern ((t-3)^2)/4

Lösung

erweitern

\frac{( t - 3 ) ^{2}}{4}

\frac{t ^{2}}{4} - \frac{3 t}{2} + \frac{9}{4}

Schritte zur Lösung

\frac{( t - 3 ) ^{2}}{4}

(t - 3)^{2} = t^{2} - 6 t + 9

= \frac{t ^{2} - 6 t + 9}{4}

Wende Bruchregel an:

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

\frac{t ^{2} - 6 t + 9}{4} = \frac{t ^{2}}{4} - \frac{6 t}{4} + \frac{9}{4}

= \frac{t ^{2}}{4} - \frac{6 t}{4} + \frac{9}{4}
