integral from-1 to 1 of (3x^2-8x)

Solution

\int_{- 1}^{1} (3 x^{2} - 8 x) d x

Solution

2

Solution steps

\int_{- 1}^{1} 3 x^{2} - 8 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_{- 1}^{1} 3 x^{2} d x - \int_{- 1}^{1} 8 x d x

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

\int_{- 1}^{1} 8 x d x = 0

= 2 - 0

Simplify

= 2
