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

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

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

Solution steps

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

Expand

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

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

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

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

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

Add a constant to the solution

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

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

\int \frac{5}{1 + e ^{x}} d x

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

\int \frac{( - 2 x + 6 )}{( x ^{2} + 2 x + 4 ) ^{2}} d x

\int \frac{x ^{2} + 10 x + 2}{x ^{3} + 15 x ^{2} + 6 x + 3} d x
