\frac{x ^{2} + 3 x + 7}{x} : x^{\frac{3}{2}} + 3 x + \frac{7}{x}

= \int x^{\frac{3}{2}} + 3 x + \frac{7}{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 x^{\frac{3}{2}} d x + \int 3 x d x + \int \frac{7}{x} d x

\int x^{\frac{3}{2}} d x = \frac{2}{5} x^{\frac{5}{2}}

\int 3 x d x = 2 x^{\frac{3}{2}}

\int \frac{7}{x} d x = 14 x

= \frac{2}{5} x^{\frac{5}{2}} + 2 x^{\frac{3}{2}} + 14 x
