integral from-4 to 4 of (x^2-2)

Solution

\int_{- 4}^{4} (x^{2} - 2) d x

Solution

\frac{80}{3}

+1

Decimal Notation

26.66666 \dots

Solution steps

\int_{- 4}^{4} x^{2} - 2 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_{- 4}^{4} x^{2} d x - \int_{- 4}^{4} 2 d x

\int_{- 4}^{4} x^{2} d x = \frac{128}{3}

\int_{- 4}^{4} 2 d x = 16

= \frac{128}{3} - 16

Simplify

\frac{128}{3} - 16 : \frac{80}{3}

= \frac{80}{3}
