integral of 8x^3-6x^{-2}

\int 8 x^{3} - 6 x^{- 2} d x

2 x^{4} + \frac{6}{x} + C

Solution steps

\int 8 x^{3} - 6 x^{- 2} d x

6 x^{- 2} = \frac{6}{x ^{2}}

= \int 8 x^{3} - \frac{6}{x ^{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 8 x^{3} d x - \int \frac{6}{x ^{2}} d x

\int 8 x^{3} d x = 2 x^{4}

\int \frac{6}{x ^{2}} d x = - \frac{6}{x}

= 2 x^{4} - (- \frac{6}{x})

Simplify

= 2 x^{4} + \frac{6}{x}

Add a constant to the solution

= 2 x^{4} + \frac{6}{x} + C
