integral from-1 to 1 of (9x^2+6x-3)

\int_{- 1}^{1} (9 x^{2} + 6 x - 3) d x

0

Solution steps

\int_{- 1}^{1} 9 x^{2} + 6 x - 3 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} 9 x^{2} d x + \int_{- 1}^{1} 6 x d x - \int_{- 1}^{1} 3 d x

\int_{- 1}^{1} 9 x^{2} d x = 6

\int_{- 1}^{1} 6 x d x = 0

\int_{- 1}^{1} 3 d x = 6

= 6 + 0 - 6

Simplify

= 0
