integral of (3x^{-2}+2)

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

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

Solution steps

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

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

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

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

\int 2 d x = 2 x

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

Add a constant to the solution

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