erweitern ((3x-11)^2)/(64)

Lösung

erweitern

\frac{( 3 x - 11 ) ^{2}}{64}

\frac{9 x ^{2}}{64} - \frac{33 x}{32} + \frac{121}{64}

Schritte zur Lösung

\frac{( 3 x - 11 ) ^{2}}{64}

(3 x - 11)^{2} = 9 x^{2} - 66 x + 121

= \frac{9 x ^{2} - 66 x + 121}{64}

Wende Bruchregel an:

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

\frac{9 x ^{2} - 66 x + 121}{64} = \frac{9 x ^{2}}{64} - \frac{66 x}{64} + \frac{121}{64}

= \frac{9 x ^{2}}{64} - \frac{66 x}{64} + \frac{121}{64}
