<em>Comment on the variable</em>
We have used the variable given in the problem statement (xx). If you intend something different, replace xx with the variable you intend.
We have that
case <span>A)
(x – 2)(x + 2)(x</span>²<span> + 8)(x4 + 8)
(x</span>²-4)(x² + 8)(x4 + 8)
case <span>B)
(x – 2)(x – 2)(x</span>²<span> + 4)(x4 + 16)
(x-2)</span>²(x² + 4)(x4 + 16)
case <span>C)
(x – 2)(x + 2)(x</span>²<span> + 4)(x4 + 16)
(x</span>²-4)(x² + 4)(x4 + 16)
(x4 -16)(x4 + 16)
(x8-256)
case <span>D)
(x + 2)(x + 2)(x</span>²<span> + 4)(x4 + 16)
(x+2)</span>²(x² + 4)(x4 + 16)
the answer is
the option
<span>C) (x – 2)(x + 2)(x2 + 4)(x4 + 16) </span>
