\frac{x ^{9} - 3 x ^{4}}{x ^{6}} : x^{3} - \frac{3}{x ^{2}}

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

\int x^{3} d x = \frac{x ^{4}}{4}

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

= \frac{x ^{4}}{4} - (- \frac{3}{x})

Vereinfache

= \frac{x ^{4}}{4} + \frac{3}{x}
