Which value of a would make the following expression completely factored? X^

ololo11 [35]

Answer:

A. 12

Step-by-step explanation:

Selecting B, C, or D would create a difference of perfect squares since each of these numbers are perfect squares. Additional factoring would then be needed.

$x^2-36 = (x+6)(x-6)\\x^2-49 = (x+7)(x-7)\\x^2-81=(x+9)(x-9)$

But selecting 12 gives $x^2-12$ which cannot be factored. It is factored completely.
