\frac{x ^{3} - x ^{2} - 4 x + 4}{x ^{3} - x ^{2} - 6 x} : \frac{x ^{3}}{x ^{3} - x ^{2} - 6 x} - \frac{x ^{2}}{x ^{3} - x ^{2} - 6 x} - \frac{4 x}{x ^{3} - x ^{2} - 6 x} + \frac{4}{x ^{3} - x ^{2} - 6 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 \frac{x ^{3}}{x ^{3} - x ^{2} - 6 x} d x - \int \frac{x ^{2}}{x ^{3} - x ^{2} - 6 x} d x - \int \frac{4 x}{x ^{3} - x ^{2} - 6 x} d x + \int \frac{4}{x ^{3} - x ^{2} - 6 x} d x

\int \frac{x ^{3}}{x ^{3} - x ^{2} - 6 x} d x = x - \frac{1}{2} - \frac{4}{5} ln ∣ 2 x + 4 ∣ + \frac{9}{5} ln ∣ 2 x - 6 ∣

\int \frac{x ^{2}}{x ^{3} - x ^{2} - 6 x} d x = \frac{2}{5} ln ∣ x + 2 ∣ + \frac{3}{5} ln ∣ x - 3 ∣

\int \frac{4 x}{x ^{3} - x ^{2} - 6 x} d x = 4 (- \frac{1}{5} ln ∣ x + 2 ∣ + \frac{1}{5} ln ∣ x - 3 ∣)

\int \frac{4}{x ^{3} - x ^{2} - 6 x} d x = 4 (- \frac{1}{6} ln ∣ x ∣ + \frac{1}{10} ln ∣ x + 2 ∣ + \frac{1}{15} ln ∣ x - 3 ∣)

= x - \frac{1}{2} - \frac{4}{5} ln ∣ 2 x + 4 ∣ + \frac{9}{5} ln ∣ 2 x - 6 ∣ - (\frac{2}{5} ln ∣ x + 2 ∣ + \frac{3}{5} ln ∣ x - 3 ∣) - 4 (- \frac{1}{5} ln ∣ x + 2 ∣ + \frac{1}{5} ln ∣ x - 3 ∣) + 4 (- \frac{1}{6} ln ∣ x ∣ + \frac{1}{10} ln ∣ x + 2 ∣ + \frac{1}{15} ln ∣ x - 3 ∣)

Vereinfache

x - \frac{1}{2} - \frac{4}{5} ln ∣ 2 x + 4 ∣ + \frac{9}{5} ln ∣ 2 x - 6 ∣ - (\frac{2}{5} ln ∣ x + 2 ∣ + \frac{3}{5} ln ∣ x - 3 ∣) - 4 (- \frac{1}{5} ln ∣ x + 2 ∣ + \frac{1}{5} ln ∣ x - 3 ∣) + 4 (- \frac{1}{6} ln ∣ x ∣ + \frac{1}{10} ln ∣ x + 2 ∣ + \frac{1}{15} ln ∣ x - 3 ∣) : x - \frac{4}{5} ln ∣ 2 x + 4 ∣ + \frac{9}{5} ln ∣ 2 x - 6 ∣ + \frac{4}{5} ln ∣ x + 2 ∣ - \frac{17}{15} ln ∣ x - 3 ∣ - \frac{2}{3} ln ∣ x ∣ - \frac{1}{2}

= x - \frac{4}{5} ln ∣ 2 x + 4 ∣ + \frac{9}{5} ln ∣ 2 x - 6 ∣ + \frac{4}{5} ln ∣ x + 2 ∣ - \frac{17}{15} ln ∣ x - 3 ∣ - \frac{2}{3} ln ∣ x ∣ - \frac{1}{2}
