integral from 2 to 3 of (x^2+3)

Solution

\int_{2}^{3} (x^{2} + 3) d x

Solution

\frac{28}{3}

+1

Decimal

9.33333 \dots

Solution steps

\int_{2}^{3} x^{2} + 3 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_{2}^{3} x^{2} d x + \int_{2}^{3} 3 d x

\int_{2}^{3} x^{2} d x = \frac{19}{3}

\int_{2}^{3} 3 d x = 3

= \frac{19}{3} + 3

Simplify

\frac{19}{3} + 3 : \frac{28}{3}

= \frac{28}{3}
