Answer:

  1. yes
  2. no
  3. no

Step-by-step explanation:

1. f(2) = 2^5 -32 = 0 . . . . (x -2) is a factor

__

2. f(5)) = (x -16)x +34 = (-11)(5) +34 = -21 . . . . (x -5) is not a factor

  We also note that 5 is not a factor of 34, so cannot be a root of f(x).

__

3. f(2) = ((x^2+4)x^2 +2)x -16 = ((4 +4)(4) +2)2 -16 = 34(2) -16 = 52

  (x -2) is not a factor
