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

Solution

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

Solution

0

Solution steps

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

\int_{- 4}^{2} x^{2} d x = 24

\int_{- 4}^{2} 4 x d x = - 24

= 24 - 24

Simplify

= 0
