integral from-2 to 0 of x^2-4x

Solution

\int_{- 2}^{0} x^{2} - 4 x d x

Solution

\frac{32}{3}

+1

Decimal

10.66666 \dots

Solution steps

\int_{- 2}^{0} x^{2} - 4 x 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}^{0} x^{2} d x - \int_{- 2}^{0} 4 x d x

\int_{- 2}^{0} x^{2} d x = \frac{8}{3}

\int_{- 2}^{0} 4 x d x = - 8

= \frac{8}{3} - (- 8)

Simplify

\frac{8}{3} - (- 8) : \frac{32}{3}

= \frac{32}{3}
