integral from-8 to 4 of-x^2-3x

Solution

\int_{- 8}^{4} - x^{2} - 3 x d x

Solution

- 120

Solution steps

\int_{- 8}^{4} - x^{2} - 3 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_{- 8}^{4} x^{2} d x - \int_{- 8}^{4} 3 x d x

\int_{- 8}^{4} x^{2} d x = 192

\int_{- 8}^{4} 3 x d x = - 72

= - 192 - (- 72)

Simplify

= - 120
