Schritte zur Lösung

\int - x x - 1 d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - \int x x - 1 d x

Wende U-Substitution an

= - \int (u + 1) u d u

Multipliziere aus

(u + 1) u : u^{\frac{3}{2}} + u

= - \int u^{\frac{3}{2}} + u d u

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= - (\int u^{\frac{3}{2}} d u + \int u d u)

\int u^{\frac{3}{2}} d u = \frac{2}{5} u^{\frac{5}{2}}

\int u d u = \frac{2}{3} u^{\frac{3}{2}}

= - (\frac{2}{5} u^{\frac{5}{2}} + \frac{2}{3} u^{\frac{3}{2}})

Setze in

u = x - 1

ein

= - (\frac{2}{5} (x - 1)^{\frac{5}{2}} + \frac{2}{3} (x - 1)^{\frac{3}{2}})

Vereinfache

= - \frac{2}{5} (x - 1)^{\frac{5}{2}} - \frac{2}{3} (x - 1)^{\frac{3}{2}}
