integral of (7+x+x^2)/(sqrt(x))

\int \frac{7 + x + x ^{2}}{x} d x

14 x + \frac{2}{3} x^{\frac{3}{2}} + \frac{2}{5} x^{\frac{5}{2}} + C

Solution steps

\int \frac{7 + x + x ^{2}}{x} d x

Expand

\frac{7 + x + x ^{2}}{x} : \frac{7}{x} + x + x^{\frac{3}{2}}

= \int \frac{7}{x} + x + x^{\frac{3}{2}} 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 \frac{7}{x} d x + \int x d x + \int x^{\frac{3}{2}} d x

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

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

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

= 14 x + \frac{2}{3} x^{\frac{3}{2}} + \frac{2}{5} x^{\frac{5}{2}}

Add a constant to the solution

= 14 x + \frac{2}{3} x^{\frac{3}{2}} + \frac{2}{5} x^{\frac{5}{2}} + C

f (x) = 8 x^{2} - x

\frac{d}{d x} (sin (\frac{π}{x}))

\frac{\partial}{\partial x} (ln (x^{3} + y^{7}))

\frac{d}{d x} (sin^{- 5} (x) - cos^{3} (x))

\int \frac{( x + 1 )}{x} d x
