u (1 - 2 u) : u - 2 u^{2}

= \int_{- 1}^{3} u - 2 u^{2} 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_{- 1}^{3} u d u - \int_{- 1}^{3} 2 u^{2} d u

\int_{- 1}^{3} u d u = 4

\int_{- 1}^{3} 2 u^{2} d u = \frac{56}{3}

= 4 - \frac{56}{3}

Vereinfache

4 - \frac{56}{3} : - \frac{44}{3}

= - \frac{44}{3}
