integral from-1 to 2 of 2x^2-3

Solution

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

Solution

- 3

Solution steps

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

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

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

= 6 - 9

Simplify

= - 3
