Lösung

erweitern

\frac{2 ( 4 x - 14 ) ^{2}}{9}

\frac{32 x ^{2}}{9} - \frac{224 x}{9} + \frac{392}{9}

Schritte zur Lösung

\frac{2 ( 4 x - 14 ) ^{2}}{9}

(4 x - 14)^{2} = 16 x^{2} - 112 x + 196

= \frac{2 ( 16 x ^{2} - 112 x + 196 )}{9}

2 (16 x^{2} - 112 x + 196) : 32 x^{2} - 224 x + 392

= \frac{32 x ^{2} - 224 x + 392}{9}

Wende Bruchregel an:

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

\frac{32 x ^{2} - 224 x + 392}{9} = \frac{32 x ^{2}}{9} - \frac{224 x}{9} + \frac{392}{9}

= \frac{32 x ^{2}}{9} - \frac{224 x}{9} + \frac{392}{9}
