integral from 0 to 3 of (2x^2-6x)

Solution

\int_{0}^{3} (2 x^{2} - 6 x) d x

Solution

- 9

Solution steps

\int_{0}^{3} 2 x^{2} - 6 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_{0}^{3} 2 x^{2} d x - \int_{0}^{3} 6 x d x

\int_{0}^{3} 2 x^{2} d x = 18

\int_{0}^{3} 6 x d x = 27

= 18 - 27

Simplify

= - 9
