integral of (2x-4+9sqrt(x))/(sqrt(x))

\int \frac{2 x - 4 + 9 x}{x} d x

\frac{4}{3} x^{\frac{3}{2}} - 8 x + 9 x + C

Solution steps

\int \frac{2 x - 4 + 9 x}{x} d x

Expand

\frac{2 x - 4 + 9 x}{x} : 2 x - \frac{4}{x} + 9

= \int 2 x - \frac{4}{x} + 9 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 2 x d x - \int \frac{4}{x} d x + \int 9 d x

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

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

\int 9 d x = 9 x

= \frac{4}{3} x^{\frac{3}{2}} - 8 x + 9 x

Add a constant to the solution

= \frac{4}{3} x^{\frac{3}{2}} - 8 x + 9 x + C

\int (sin (x))^{5} (cos (x))^{6} d x

\int \frac{cos ( x ) + sin ( x )}{cos ( x )} d x

\int \frac{x + 2}{x x + 1} d x

\int \frac{y ^{2}}{( 9 - y ^{2} ) ^{\frac{3}{2}}} d y

\int (10 x^{4} - 2 e^{x}) d x
