integral from 0 to 3 of-x^2+4x

Solution

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

Solution

9

Solution steps

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

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

\int_{0}^{3} 4 x d x = 18

= - 9 + 18

Simplify

= 9
