D) prime

Quizplus · Accepted Answer

The given expression does not seem to have any common factors or be able to be factored using any common techniques. Therefore, it is likely prime. However, none of the answer choices reflect a prime expression. So, the only answer choice left is C, which is a completely different expression entirely, so it cannot be factored any further into the original expression. The given expression follows the form of a difference of squares: (a^2 - b^2) = (a+b)(a-b). So, we can rewrite the expression as (z+6)(z-6), which is fully factored.
