integral from 4 to 8 of x^3-2x+1

Solution

\int_{4}^{8} x^{3} - 2 x + 1 d x

Solution

916

Solution steps

\int_{4}^{8} x^{3} - 2 x + 1 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_{4}^{8} x^{3} d x - \int_{4}^{8} 2 x d x + \int_{4}^{8} 1 d x

\int_{4}^{8} x^{3} d x = 960

\int_{4}^{8} 2 x d x = 48

\int_{4}^{8} 1 d x = 4

= 960 - 48 + 4

Simplify

= 916
