\frac{2 x + 7}{9 - 4 x ^{2}} : \frac{2 x}{9 - 4 x ^{2}} + \frac{7}{9 - 4 x ^{2}}

= \int \frac{2 x}{9 - 4 x ^{2}} + \frac{7}{9 - 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 \frac{2 x}{9 - 4 x ^{2}} d x + \int \frac{7}{9 - 4 x ^{2}} d x

\int \frac{2 x}{9 - 4 x ^{2}} d x = - \frac{1}{2} 9 - 4 x^{2}

\int \frac{7}{9 - 4 x ^{2}} d x = \frac{7}{2} arcsin (\frac{2}{3} x)

= - \frac{1}{2} 9 - 4 x^{2} + \frac{7}{2} arcsin (\frac{2}{3} x)
