integral from-1 to 2 of (7-6x^2)

Solution

\int_{- 1}^{2} (7 - 6 x^{2}) d x

Solution

3

Solution steps

\int_{- 1}^{2} 7 - 6 x^{2} 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}^{2} 7 d x - \int_{- 1}^{2} 6 x^{2} d x

\int_{- 1}^{2} 7 d x = 21

\int_{- 1}^{2} 6 x^{2} d x = 18

= 21 - 18

Simplify

= 3
