Q. Use the Fundamental Theorem of Algebra to find the number of complex roots of the polynomial, including any repeated roots. \newlinex6+x5+3x2x+15x^6 +x^5 + 3x^2 - x + 15 \newline____
  1. Degree of the Polynomial: The degree of the polynomial x6+x5+3x2x+15x^6 + x^5 + 3x^2 - x + 15 is 66, because the highest power of xx is 66.
  2. Fundamental Theorem of Algebra: According to the Fundamental Theorem of Algebra, a polynomial of degree nn has exactly nn complex roots, counting multiplicity.
  3. Complex Roots: Therefore, the polynomial x6+x5+3x2x+15x^6 + x^5 + 3x^2 - x + 15 has 66 complex roots.
