Schritte zur Lösung

\int_{1}^{2} 2 x - x^{2} 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_{1}^{2} 2 x d x - \int_{1}^{2} x^{2} d x

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

\int_{1}^{2} x^{2} d x = \frac{7}{3}

= 3 - \frac{7}{3}

Vereinfache

3 - \frac{7}{3} : \frac{2}{3}

= \frac{2}{3}
