integral of 2x+5x^{-2}

Lösung

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

Lösung

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

Schritte zur Lösung

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

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

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

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

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

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

Füge eine Konstante zur Lösung hinzu

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