Select the expression that is equivalent to the given polynomial.
16r4 – 625
O A. (2x + 5)(2x - 5)(2x + 5i) (2x – 5i)
B. (2x - 5)(2x – 5)(2x – 5i)(2x – 5i)
C. (2x - 5)(2x – 5)(2x + 5i)(2x – 5i)
D. (2x + 5)(2x + 5)(2x + 5) (21 + 5i)

Observe that is the square of , and 625 is the square of 25.

So, your expression is a difference of squares, and as such we can rewrite it as

Now again, is the square of , and 25 is the square of 5. So, we have a sum and a difference of squares.

But if we think of 25 as , we have again the difference of two squares, so we have
