integral of (x+1)(2x^2+sqrt(x))

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

(x + 1) (\frac{2 x ^{3}}{3} + \frac{2}{3} x^{\frac{3}{2}}) - \frac{1}{3} (\frac{x ^{4}}{2} + \frac{4}{5} x^{\frac{5}{2}}) + C

Solution steps

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

Apply Integration By Parts

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

\int \frac{1}{3} (2 x^{3} + 2 x^{\frac{3}{2}}) d x = \frac{1}{3} (\frac{x ^{4}}{2} + \frac{4}{5} x^{\frac{5}{2}})

= (x + 1) (\frac{2 x ^{3}}{3} + \frac{2}{3} x^{\frac{3}{2}}) - \frac{1}{3} (\frac{x ^{4}}{2} + \frac{4}{5} x^{\frac{5}{2}})

Add a constant to the solution

= (x + 1) (\frac{2 x ^{3}}{3} + \frac{2}{3} x^{\frac{3}{2}}) - \frac{1}{3} (\frac{x ^{4}}{2} + \frac{4}{5} x^{\frac{5}{2}}) + C
