integral of 4sqrt(x)-4/(sqrt(x))

\int 4 x - \frac{4}{x} d x

\frac{8}{3} x^{\frac{3}{2}} - 8 x + C

Solution steps

\int 4 x - \frac{4}{x} 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 4 x d x - \int \frac{4}{x} d x

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

\int \frac{4}{x} d x = 8 x

= \frac{8}{3} x^{\frac{3}{2}} - 8 x

Add a constant to the solution

= \frac{8}{3} x^{\frac{3}{2}} - 8 x + C
