integral of ((3x^3-4x-2)/(x^3))

\int (\frac{3 x ^{3} - 4 x - 2}{x ^{3}}) d x

3 x + \frac{4}{x} + \frac{1}{x ^{2}} + C

Solution steps

\int \frac{3 x ^{3} - 4 x - 2}{x ^{3}} d x

Expand

\frac{3 x ^{3} - 4 x - 2}{x ^{3}} : 3 - \frac{4}{x ^{2}} - \frac{2}{x ^{3}}

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

\int 3 d x = 3 x

\int \frac{4}{x ^{2}} d x = - \frac{4}{x}

\int \frac{2}{x ^{3}} d x = - \frac{1}{x ^{2}}

= 3 x - (- \frac{4}{x}) - (- \frac{1}{x ^{2}})

Simplify

= 3 x + \frac{4}{x} + \frac{1}{x ^{2}}

Add a constant to the solution

= 3 x + \frac{4}{x} + \frac{1}{x ^{2}} + C

f (x) = \frac{6 x}{x ^{2} + 1}, (1, 3)

\frac{\partial}{\partial y} (\frac{x y ^{2}}{z ^{3}})

\frac{d}{d x} (\frac{e ^{2 x}}{x ^{2} + 1})

\int_{0}^{1} e^{x} - x e^{x} d x

\int_{x}^{0.5} 8 d y
