integral from 0 to 4 of x(x^2-1)

Solution

\int_{0}^{4} x (x^{2} - 1) d x

Solution

56

Solution steps

\int_{0}^{4} x (x^{2} - 1) d x

Expand

x (x^{2} - 1) : x^{3} - x

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

\int_{0}^{4} x^{3} d x = 64

\int_{0}^{4} x d x = 8

= 64 - 8

Simplify

= 56
