Q. Use the Fundamental Theorem of Algebra to find the number of complex roots of the polynomial, including any repeated roots. x6+x4−12x3+17x2−9x+15____
Identify Highest Power: Look at the polynomial x6+x4−12x3+17x2−9x+15 and find the highest power of x. The highest power of x is 6.
Apply Fundamental Theorem: According to the Fundamental Theorem of Algebra, a polynomial of degree n has exactly n complex roots, counting multiplicity.So, this polynomial should have 6 complex roots.
Verify Degree and Theorem: Check if the degree of the polynomial is correctly identified and if the Fundamental Theorem of Algebra is applied correctly.Degree identified: 6Theorem applied correctly: Yes
