Answer

approximately $\color{blue}{-1.769}$.

Work Step by Step

Using a graphing utility to graph the function $y=x^3-2x+2$ (refer to the attached image below for the graph) The solution to the given equation is the x-coordinate of the point where the graph is equal to zero. Note that the graph's value is zero at the point $(-1.769, 0)$. Therefore, the solution to the given equation is approximately $\color{blue}{-1.769}$.
