According to the Fundamental Theorem of Algebra, which polynomial function has exactly 6 roots?
Paul [167]

Answer: d.f(x)=7x^6+3x^3+12


Explanation:-

  • The fundamental theorem of algebra tells that every non-constant single-variable polynomial with complex coefficients has at least one complex root.
  • Corollary to the fundamental theorem tells that every polynomial of m>0 degree has exactly m zeroes.

Thus only option d.f(x)=7x^6+3x^3+12 with degree 6 has exactly 6 roots.
