integral of 9x^2-4x

Lösung

\int 9 x^{2} - 4 x d x

Lösung

3 x^{3} - 2 x^{2} + C

Schritte zur Lösung

\int 9 x^{2} - 4 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 9 x^{2} d x - \int 4 x d x

\int 9 x^{2} d x = 3 x^{3}

\int 4 x d x = 2 x^{2}

= 3 x^{3} - 2 x^{2}

Füge eine Konstante zur Lösung hinzu

= 3 x^{3} - 2 x^{2} + C
