integral from-2 to 2 of x^2+5

Solution

\int_{- 2}^{2} x^{2} + 5 d x

Solution

\frac{76}{3}

+1

Decimal

25.33333 \dots

Solution steps

\int_{- 2}^{2} x^{2} + 5 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} 5 d x

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

\int_{- 2}^{2} 5 d x = 20

= \frac{16}{3} + 20

Simplify

\frac{16}{3} + 20 : \frac{76}{3}

= \frac{76}{3}
