Q. Use the Fundamental Theorem of Algebra to find the number of complex roots of the polynomial, including any repeated roots. −2x4+17x3+12x2−3____
Find Polynomial Degree: Look at the polynomial: −2x4+17x3+12x2−3. What's the degree of the polynomial?The highest power of x is 4, so the degree is 4.
Fundamental Theorem of Algebra: According to the Fundamental Theorem of Algebra, a polynomial of degree n has exactly n complex roots, counting multiplicity.So, this polynomial will have 4 complex roots.
