integral from 0 to 3 of sqrt(x)(x+1)

\int_{0}^{3} x (x + 1) d x

\frac{18 3}{5} + 23

Decimal

9.69948 \dots

Solution steps

\int_{0}^{3} x (x + 1) d x

Expand

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

= \int_{0}^{3} x^{\frac{3}{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_{0}^{3} x^{\frac{3}{2}} d x + \int_{0}^{3} x d x

\int_{0}^{3} x^{\frac{3}{2}} d x = \frac{18 3}{5}

\int_{0}^{3} x d x = 23

= \frac{18 3}{5} + 23
