\frac{3 x ^{6} + 4 x ^{2} + 12}{x ^{4}} : 3 x^{2} + \frac{4}{x ^{2}} + \frac{12}{x ^{4}}

= \int 3 x^{2} + \frac{4}{x ^{2}} + \frac{12}{x ^{4}} 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 3 x^{2} d x + \int \frac{4}{x ^{2}} d x + \int \frac{12}{x ^{4}} d x

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

\int \frac{4}{x ^{2}} d x = - \frac{4}{x}

\int \frac{12}{x ^{4}} d x = - \frac{4}{x ^{3}}

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

Füge eine Konstante zur Lösung hinzu

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