\frac{4 x + 6}{( x + 1 ) ^{2}} : \frac{4 x}{( x + 1 ) ^{2}} + \frac{6}{( x + 1 ) ^{2}}

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{1} \frac{4 x}{( x + 1 ) ^{2}} d x + \int_{0}^{1} \frac{6}{( x + 1 ) ^{2}} d x

\int_{0}^{1} \frac{4 x}{( x + 1 ) ^{2}} d x = 4 (ln (2) - \frac{1}{2})

\int_{0}^{1} \frac{6}{( x + 1 ) ^{2}} d x = 3

= 4 (ln (2) - \frac{1}{2}) + 3

Vereinfache

4 (ln (2) - \frac{1}{2}) + 3 : 4 ln (2) + 1

= 4 ln (2) + 1
