Schritte zur Lösung

\int_{0}^{1} - x^{2} - x^{3} + 2 x d x

Wende die Summenregel an:

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

= - \int_{0}^{1} x^{2} d x - \int_{0}^{1} x^{3} d x + \int_{0}^{1} 2 x d x

\int_{0}^{1} x^{2} d x = \frac{1}{3}

\int_{0}^{1} x^{3} d x = \frac{1}{4}

\int_{0}^{1} 2 x d x = 1

= - \frac{1}{3} - \frac{1}{4} + 1

Vereinfache

- \frac{1}{3} - \frac{1}{4} + 1 : \frac{5}{12}

= \frac{5}{12}

\int_{- 2}^{x} (28 t^{2} - 27 t) d t
