integral from-1 to 1 of (x^2-2)

Solution

\int_{- 1}^{1} (x^{2} - 2) d x

Solution

- \frac{10}{3}

+1

Decimal Notation

- 3.33333 \dots

Solution steps

\int_{- 1}^{1} 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_{- 1}^{1} x^{2} d x - \int_{- 1}^{1} 2 d x

\int_{- 1}^{1} x^{2} d x = \frac{2}{3}

\int_{- 1}^{1} 2 d x = 4

= \frac{2}{3} - 4

Simplify

\frac{2}{3} - 4 : - \frac{10}{3}

= - \frac{10}{3}
