Lösung

erweitern

\frac{( 4 x ^{4} - 1 ) ^{2}}{4 x ^{2}}

4 x^{6} - 2 x^{2} + \frac{1}{4 x ^{2}}

Schritte zur Lösung

\frac{( 4 x ^{4} - 1 ) ^{2}}{4 x ^{2}}

(4 x^{4} - 1)^{2} = 16 x^{8} - 8 x^{4} + 1

= \frac{16 x ^{8} - 8 x ^{4} + 1}{4 x ^{2}}

Wende Bruchregel an:

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

\frac{16 x ^{8} - 8 x ^{4} + 1}{4 x ^{2}} = \frac{16 x ^{8}}{4 x ^{2}} - \frac{8 x ^{4}}{4 x ^{2}} + \frac{1}{4 x ^{2}}

= \frac{16 x ^{8}}{4 x ^{2}} - \frac{8 x ^{4}}{4 x ^{2}} + \frac{1}{4 x ^{2}}

Streiche

\frac{16 x ^{8}}{4 x ^{2}} : 4 x^{6}
