integral from-2 to 2 of-2x^2+8

Solution

\int_{- 2}^{2} - 2 x^{2} + 8 d x

Solution

\frac{64}{3}

+1

Decimal Notation

21.33333 \dots

Solution steps

\int_{- 2}^{2} - 2 x^{2} + 8 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} 2 x^{2} d x + \int_{- 2}^{2} 8 d x

\int_{- 2}^{2} 2 x^{2} d x = \frac{32}{3}

\int_{- 2}^{2} 8 d x = 32

= - \frac{32}{3} + 32

Simplify

- \frac{32}{3} + 32 : \frac{64}{3}

= \frac{64}{3}
