A real root of fifth-grade multiplicity/No complex roots.
Step-by-step explanation:
The Fundamental Theorem of Algebra states that every polynomial with real coefficients and a grade greater than zero has at least a real root. Let be , if such expression is equalized to zero and handled algebraically:
1) Given.
2) Definition of power.
3) Given.
4) Compatibility with the addition/Existence of the additive inverse/Modulative property/Result.
This expression has a real root of fifth-grade multiplicity. No complex roots.
