One factor of is (x – 2). What are all the roots of the function? use the remainder theorem. X = 1, x = 2, or x = 4 x = –2, x = 1, or x = 2 x = 2, x = 4, or x = 16 x = –16, x = 2, or x = 16.
The remainder theorem says that if is a factor of a polynomial , then the remainder upon dividing is 0 so that there exists a lower degree polynomial as the quotient:
