integral from 0 to 4 of x^2+x

Solution

\int_{0}^{4} x^{2} + x d x

Solution

\frac{88}{3}

+1

Decimal

29.33333 \dots

Solution steps

\int_{0}^{4} x^{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}^{4} x^{2} d x + \int_{0}^{4} x d x

\int_{0}^{4} x^{2} d x = \frac{64}{3}

\int_{0}^{4} x d x = 8

= \frac{64}{3} + 8

Simplify

\frac{64}{3} + 8 : \frac{88}{3}

= \frac{88}{3}
