Schritte zur Lösung

\int_{- 2}^{0} \frac{x}{( x ^{2} + 3 ) ^{2}} d x

Wende U-Substitution an

= \int_{7}^{3} \frac{1}{2 u ^{2}} d u

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

= - \int_{3}^{7} \frac{1}{2 u ^{2}} d u

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - \frac{1}{2} \cdot \int_{3}^{7} \frac{1}{u ^{2}} d u

Wende die Potenzregel an

= - \frac{1}{2} [- \frac{1}{u}]_{3}^{7}

Berechne die Grenzen:

\frac{4}{21}

= - \frac{1}{2} \cdot \frac{4}{21}

Vereinfache

= - \frac{2}{21}
