Answer: There are 3 roots.

Explanation:

Since the degree of this equation is 3, we will assume that we have three roots. That said, there may be some roots with a multiplicity of 2 or more. Since this is possible, we will graph the equation and see how many times the line intercepts the x-axis. We see that there are 3, giving us an answer of 3 roots.
