According to the fundamental theorem of algebra, which polynomial function has exactly 8 roots? f(x) 3x4 +2xfox)- (6x -4x5-10 3x2-4

The number of roots of a polynomial is determined by the highest power of the variable after all simplifications has been done. For the first option, after the brackets has been expanded, the highest power of x will be 8. The second option will have the highest power of x as 16. The third option will have the highest power of x as 6 while the last option will have the highest power of x as 10. Therefore, the polynomial function with exactly 8 roots is f(x) = (3x^2 - 4x - 5)(2x^6 - 5).

32.10 is the correct answer
