erweitern (2x^3-1)/(x^2)

Lösung

erweitern

\frac{2 x ^{3} - 1}{x ^{2}}

2 x - \frac{1}{x ^{2}}

Schritte zur Lösung

\frac{2 x ^{3} - 1}{x ^{2}}

Wende Bruchregel an:

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

\frac{2 x ^{3} - 1}{x ^{2}} = \frac{2 x ^{3}}{x ^{2}} - \frac{1}{x ^{2}}

= \frac{2 x ^{3}}{x ^{2}} - \frac{1}{x ^{2}}
