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

Lösung

\int \frac{x ^{2} - x}{( x - 2 ) ( x - 3 ) ^{2}} d x

Lösung

2 ln ∣ x - 2 ∣ - ln ∣ x - 3 ∣ - \frac{6}{x - 3} + C

Schritte zur Lösung

\int \frac{x ^{2} - x}{( x - 2 ) ( x - 3 ) ^{2}} d x

Ermittle den Partialbruch von

\frac{x ^{2} - x}{( x - 2 ) ( x - 3 ) ^{2}} : \frac{2}{x - 2} - \frac{1}{x - 3} + \frac{6}{( x - 3 ) ^{2}}

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

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

\int \frac{1}{x - 3} d x = ln ∣ x - 3 ∣

\int \frac{6}{( x - 3 ) ^{2}} d x = - \frac{6}{x - 3}

= 2 ln ∣ x - 2 ∣ - ln ∣ x - 3 ∣ - \frac{6}{x - 3}

Füge eine Konstante zur Lösung hinzu

= 2 ln ∣ x - 2 ∣ - ln ∣ x - 3 ∣ - \frac{6}{x - 3} + C
