9 f x (\frac{2}{3} - x) d x

6 f x d x - 9 f x^{2} d x

Schritte zur Lösung

9 f x (\frac{2}{3} - x) d x

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = 9 f x d x, b = \frac{2}{3}, c = x

= 9 f x d x \frac{2}{3} - 9 f x d xx

= 9 \cdot \frac{2}{3} f x d x - 9 f xx d x

Vereinfache

9 \cdot \frac{2}{3} f x d x - 9 f xx d x : 6 f x d x - 9 f x^{2} d x

= 6 f x d x - 9 f x^{2} d x
