(x - 1)^{2} : x^{2} - 2 x + 1

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

\int_{2}^{3} x^{2} d x = \frac{19}{3}

\int_{2}^{3} 2 x d x = 5

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

= \frac{19}{3} - 5 + 1

Vereinfache

\frac{19}{3} - 5 + 1 : \frac{7}{3}

= \frac{7}{3}

\int_{- 6}^{3} - x^{2} - 3 x d x
