integral of (1/(x^2)+5x-2)

Lösung

\int (\frac{1}{x ^{2}} + 5 x - 2) d x

- \frac{1}{x} + \frac{5 x ^{2}}{2} - 2 x + C

Schritte zur Lösung

\int \frac{1}{x ^{2}} + 5 x - 2 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 \frac{1}{x ^{2}} d x + \int 5 x d x - \int 2 d x

\int \frac{1}{x ^{2}} d x = - \frac{1}{x}

\int 5 x d x = \frac{5 x ^{2}}{2}

\int 2 d x = 2 x

= - \frac{1}{x} + \frac{5 x ^{2}}{2} - 2 x
