Answer

$0.75$

Step-by-step explanation

Problem to solve:

$\int_{-1}^{2}\left(x^3-2x\right)dx$
1

The integral of a sum of two or more functions is equal to the sum of their integrals

$\int_{-1}^{2} x^3dx+\int_{-1}^{2}-2xdx$
2

Take the constant out of the integral

$\int_{-1}^{2} x^3dx-2\int_{-1}^{2} xdx$
