integral of x^2-3x-18

Lösung

\int x^{2} - 3 x - 18 d x

Lösung

\frac{x ^{3}}{3} - \frac{3 x ^{2}}{2} - 18 x + C

Schritte zur Lösung

\int x^{2} - 3 x - 18 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 x^{2} d x - \int 3 x d x - \int 18 d x

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

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

\int 18 d x = 18 x

= \frac{x ^{3}}{3} - \frac{3 x ^{2}}{2} - 18 x

Füge eine Konstante zur Lösung hinzu

= \frac{x ^{3}}{3} - \frac{3 x ^{2}}{2} - 18 x + C
