x (x - 1) : x^{2} - x

= \int_{0}^{2} x^{2} - x 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_{0}^{2} x^{2} d x - \int_{0}^{2} x d x

\int_{0}^{2} x^{2} d x = \frac{8}{3}

\int_{0}^{2} x d x = 2

= \frac{8}{3} - 2

Vereinfache

\frac{8}{3} - 2 : \frac{2}{3}

= \frac{2}{3}

\int_{0}^{1} 17 x e^{x} d x

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

\int_{0}^{7} ∣ x - 4 ∣ d x

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

\int_{- 1}^{5} x d x
