integral of (-2/(x^2)+3sqrt(x))

Lösung

\int (- \frac{2}{x ^{2}} + 3 x) d x

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

Schritte zur Lösung

\int - \frac{2}{x ^{2}} + 3 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 \frac{2}{x ^{2}} d x + \int 3 x d x

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

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

= - (- \frac{2}{x}) + 2 x^{\frac{3}{2}}

Vereinfache

= \frac{2}{x} + 2 x^{\frac{3}{2}}
