Answer: The factor form of the function F(x) is
, where
gives two complex roots.
Explanation:
The given function is,

According to the rational root theorem 1 and -1 are the possible roots of each polynomial.
Put x=-1

Since the value of F(x) is 0 at x=-1 therefore the -1 is a root of given polynomial and (x+1) is a factor of F(x).
Use synthetic division method to divide the polynomial by (x+1).
The last row of the synthetic division shows the coefficient of remaining polynomial.

At x=2 the value of F(x) is 0, therefore (x-2) is a factor of F(x).
Use synthetic division method to divide the polynomial by (x-2).

Therefore the roots of F(x) are,


Where
factors with real root and
are factors with complex roots.
To do this problem, you need to use the Pythagorean thermion I think.
