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

Solution

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

Solution

\frac{52}{3}

+1

Decimal

17.33333 \dots

Solution steps

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

\int_{- 2}^{2} x^{2} d x = \frac{16}{3}

\int_{- 2}^{2} 3 d x = 12

= \frac{16}{3} + 12

Simplify

\frac{16}{3} + 12 : \frac{52}{3}

= \frac{52}{3}
