Final answer:
The polynomial
has 3 roots, including real and complex roots, according to the Fundamental Theorem of Algebra.
Step-by-step explanation:
The polynomial given is
. According to the Fundamental Theorem of Algebra, every non-constant single-variable polynomial with complex coefficients has as many complex roots as its degree, counting each root up to its multiplicity. Thus, the cubic polynomial given would have 3 roots, including real roots and complex roots (if any).
