Schritte zur Lösung

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

\int_{0}^{3} x^{2} d x = 9

\int_{0}^{3} 3 x d x = \frac{27}{2}

= - 9 + \frac{27}{2}

Vereinfache

- 9 + \frac{27}{2} : \frac{9}{2}

= \frac{9}{2}
