Schritte zur Lösung

\int \frac{16 x ^{3} - 32 x ^{2} + 5}{x ^{2} - 2 x} d x

Lange Division

\frac{16 x ^{3} - 32 x ^{2} + 5}{x ^{2} - 2 x} : 16 x + \frac{5}{x ^{2} - 2 x}

= \int 16 x + \frac{5}{x ^{2} - 2 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 16 x d x + \int \frac{5}{x ^{2} - 2 x} d x

\int 16 x d x = 8 x^{2}

\int \frac{5}{x ^{2} - 2 x} d x = - 5 (\frac{1}{2} ln ∣ x ∣ - \frac{1}{2} ln ∣ x - 2 ∣)

= 8 x^{2} - 5 (\frac{1}{2} ln ∣ x ∣ - \frac{1}{2} ln ∣ x - 2 ∣)
