\frac{u + 5}{u ^{2}} : \frac{1}{u} + \frac{5}{u ^{2}}

= 4 \cdot \int_{- 5}^{- 1} \frac{1}{u} + \frac{5}{u ^{2}} d u

Wende die Summenregel an:

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

= 4 (\int_{- 5}^{- 1} \frac{1}{u} d u + \int_{- 5}^{- 1} \frac{5}{u ^{2}} d u)

\int_{- 5}^{- 1} \frac{1}{u} d u = - ln (5)

\int_{- 5}^{- 1} \frac{5}{u ^{2}} d u = 4

= 4 (- ln (5) + 4)

y^{^{'}} + 4 y = 8

\frac{d}{d x} (z (x) x)

\int 8 x^{\frac{3}{5}} + 5 x^{- \frac{4}{5}} d x

\int \frac{48 x ^{2}}{( x - 15 ) ( x + 5 ) ^{2}} d x
