Question

Select the correct answer. which expression is equivalent to this polynomial? 16x2 4 a. (4x 2i)(4x − 2i) b. (4x 2)(4x − 2) c. (4x 2)2 d. (4x − 2i)2

Answer 1

The correct option is b (4x+2)(4x-2).

Assuming that the expression is
`16x^2-4`, we can factorize the expression as follows:

`16x^2-4=(4x)^2-(2)^2\\ 16x^2-4=(4x+2)(4x-2)`

Note that we can further simplify the expression as:

4(2x+1)(2x-1)
