(x - 4)^{2} : x^{2} - 8 x + 16

= \frac{1}{72} \cdot \int_{4}^{x} x^{2} - 8 x + 16 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

= \frac{1}{72} (\int_{4}^{x} x^{2} d x - \int_{4}^{x} 8 x d x + \int_{4}^{x} 16 d x)

\int_{4}^{x} x^{2} d x = \frac{x ^{3} - 64}{3}

\int_{4}^{x} 8 x d x = 8 (\frac{x ^{2}}{2} - 8)

\int_{4}^{x} 16 d x = 16 x - 64

= \frac{1}{72} (\frac{x ^{3} - 64}{3} - 8 (\frac{x ^{2}}{2} - 8) + 16 x - 64)
