integral of (x^2)/(x^2-3x+2)

Lösung

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

Lösung

x - ln ∣ x - 1 ∣ + 4 ln ∣ x - 2 ∣ + C

Schritte zur Lösung

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

Ermittle den Partialbruch von

\frac{x ^{2}}{x ^{2} - 3 x + 2} : 1 - \frac{1}{x - 1} + \frac{4}{x - 2}

= \int 1 - \frac{1}{x - 1} + \frac{4}{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 1 d x - \int \frac{1}{x - 1} d x + \int \frac{4}{x - 2} d x

\int 1 d x = x

\int \frac{1}{x - 1} d x = ln ∣ x - 1 ∣

\int \frac{4}{x - 2} d x = 4 ln ∣ x - 2 ∣

= x - ln ∣ x - 1 ∣ + 4 ln ∣ x - 2 ∣

Füge eine Konstante zur Lösung hinzu

= x - ln ∣ x - 1 ∣ + 4 ln ∣ x - 2 ∣ + C
