integral of x(x+3)^{1/2}

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

\frac{2}{3} x (x + 3)^{\frac{3}{2}} - \frac{4}{15} (x + 3)^{\frac{5}{2}} + C

Solution steps

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

Apply Integration By Parts

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

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

\int \frac{2}{3} (x + 3)^{\frac{3}{2}} d x = \frac{4}{15} (x + 3)^{\frac{5}{2}}

= \frac{2}{3} x (x + 3)^{\frac{3}{2}} - \frac{4}{15} (x + 3)^{\frac{5}{2}}

Add a constant to the solution

= \frac{2}{3} x (x + 3)^{\frac{3}{2}} - \frac{4}{15} (x + 3)^{\frac{5}{2}} + C

\int \frac{1}{7 x - 9} d x

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

\int x ln (5 x) - x d x

\int cos (5 x) cos (11 x) d x

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