integral from 0 to 3 of (x^2-4)

Solution

\int_{0}^{3} (x^{2} - 4) d x

Solution

- 3

Solution steps

\int_{0}^{3} x^{2} - 4 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_{0}^{3} x^{2} d x - \int_{0}^{3} 4 d x

\int_{0}^{3} x^{2} d x = 9

\int_{0}^{3} 4 d x = 12

= 9 - 12

Simplify

= - 3
