\int_{2}^{6} - (x^{2} - 7 x + 6) d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - \int_{2}^{6} x^{2} - 7 x + 6 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_{2}^{6} x^{2} d x - \int_{2}^{6} 7 x d x + \int_{2}^{6} 6 d x)

\int_{2}^{6} x^{2} d x = \frac{208}{3}

\int_{2}^{6} 7 x d x = 112

\int_{2}^{6} 6 d x = 24

= - (\frac{208}{3} - 112 + 24)

Vereinfache

- (\frac{208}{3} - 112 + 24) : \frac{56}{3}

= \frac{56}{3}
