integral of x^2-7x+9

Lösung

\int x^{2} - 7 x + 9 d x

Lösung

\frac{x ^{3}}{3} - \frac{7 x ^{2}}{2} + 9 x + C

Schritte zur Lösung

\int x^{2} - 7 x + 9 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 7 x d x + \int 9 d x

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

\int 7 x d x = \frac{7 x ^{2}}{2}

\int 9 d x = 9 x

= \frac{x ^{3}}{3} - \frac{7 x ^{2}}{2} + 9 x

Füge eine Konstante zur Lösung hinzu

= \frac{x ^{3}}{3} - \frac{7 x ^{2}}{2} + 9 x + C
