\The remainder theorem is " If a polynomial f(x) is divided by
, the remainder is r = f(k) ".
The factor theorem is " A polynomial f(x) has a factor
".
The polynomial function
.
From (c) result
is a factor of polynomial g(x).

By using remainder theorem
and by using factor theorem
is a factor of f(x).
By the resulting quadratic expression factor as 

(Simplify)
The complete factorization of g(x) is
.
To find the real zeros of the function, set g(x) equal to zero.
\
(1st set equal to zero)
(2nd set equal to zero)
The complete factorization of g(x) is
.
