Dezimale

Schritte zur Lösung

\int_{- 3}^{- 1} 2 x^{2} + 3 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_{- 3}^{- 1} 2 x^{2} d x + \int_{- 3}^{- 1} 3 d x

\int_{- 3}^{- 1} 2 x^{2} d x = \frac{52}{3}

\int_{- 3}^{- 1} 3 d x = 6

= \frac{52}{3} + 6

Vereinfache

\frac{52}{3} + 6 : \frac{70}{3}

= \frac{70}{3}
