Schritte zur Lösung

\int_{1}^{4} 3 x^{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_{1}^{4} 3 x^{2} d x + \int_{1}^{4} x d x

\int_{1}^{4} 3 x^{2} d x = 63

\int_{1}^{4} x d x = \frac{14}{3}

= 63 + \frac{14}{3}

Vereinfache

63 + \frac{14}{3} : \frac{203}{3}

= \frac{203}{3}
