integral of (5x^3-7sqrt(x))/x

\int \frac{5 x ^{3} - 7 x}{x} d x

\frac{5 x ^{3}}{3} - 14 x + C

Solution steps

\int \frac{5 x ^{3} - 7 x}{x} d x

Expand

\frac{5 x ^{3} - 7 x}{x} : 5 x^{2} - \frac{7}{x}

= \int 5 x^{2} - \frac{7}{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 5 x^{2} d x - \int \frac{7}{x} d x

\int 5 x^{2} d x = \frac{5 x ^{3}}{3}

\int \frac{7}{x} d x = 14 x

= \frac{5 x ^{3}}{3} - 14 x

Add a constant to the solution

= \frac{5 x ^{3}}{3} - 14 x + C

\int (b + x)^{3} d x

\int \frac{x ^{3}}{1} d x

\int 2 cos (e^{x}) - 2 x e^{x} sin (e^{x}) d x

\int \frac{( 9 x ^{3} - 7 x + 2 )}{x ^{3} - x ^{2}} d x

\int (x^{2} + 1) (x^{3} + 3 x)^{- 5} d x
