Q. Use the Fundamental Theorem of Algebra to find the number of complex roots of the polynomial, including any repeated roots. \newline6x5+18x39x2+196x^5 + 18x^3 - 9x^2 + 19\newline____
  1. Find Highest Power: Look at the polynomial 6x5+18x39x2+196x^5 + 18x^3 - 9x^2 + 19 and find the highest power of xx. The highest power of xx is 55.
  2. Fundamental Theorem of Algebra: According to the Fundamental Theorem of Algebra, a polynomial of degree nn has exactly nn complex roots, counting multiplicities.\newlineSo, a 55th-degree polynomial has 55 complex roots.
  3. Number of Complex Roots: Therefore, the polynomial 6x5+18x39x2+196x^5 + 18x^3 - 9x^2 + 19 has 55 complex roots.
