Schritte zur Lösung

\int_{1}^{4} x^{2} - 3 x + 12 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} x^{2} d x - \int_{1}^{4} 3 x d x + \int_{1}^{4} 12 d x

\int_{1}^{4} x^{2} d x = 21

\int_{1}^{4} 3 x d x = \frac{45}{2}

\int_{1}^{4} 12 d x = 36

= 21 - \frac{45}{2} + 36

Vereinfache

21 - \frac{45}{2} + 36 : \frac{69}{2}

= \frac{69}{2}
