integral from-1 to 3 of (x^3-3x^2)

\int_{- 1}^{3} (x^{3} - 3 x^{2}) d x

- 8

Solution steps

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

\int_{- 1}^{3} x^{3} d x = 20

\int_{- 1}^{3} 3 x^{2} d x = 28

= 20 - 28

Simplify

= - 8
