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

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

\frac{x ^{3}}{3} - 4 x + C

Solution steps

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

Expand

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

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

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

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

= \frac{x ^{3}}{3} - 4 x

Add a constant to the solution

= \frac{x ^{3}}{3} - 4 x + C

\frac{d}{d x} (\frac{3 x + 6}{2 x + 3})

y^{^{''}} + 80 y^{^{'}} + 1200 y = 0

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

d er i v a t i v e \frac{2}{( 3 x ^{2} + 7 ) ^{2}}

s l o p e f (x) = 9 x
