integral from 2 to 5 of (x^2-8x+12)

Lösung

\int_{2}^{5} (x^{2} - 8 x + 12) d x

- 9

Schritte zur Lösung

\int_{2}^{5} x^{2} - 8 x + 12 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_{2}^{5} x^{2} d x - \int_{2}^{5} 8 x d x + \int_{2}^{5} 12 d x

\int_{2}^{5} x^{2} d x = 39

\int_{2}^{5} 8 x d x = 84

\int_{2}^{5} 12 d x = 36

= 39 - 84 + 36
