Which of the following is one of the special product formulas?

Answer: perfect square trinomials

Step-by-step explanation:

Although you don't provide the 4 multiple choice answers, here they are:

a) perfect square monomials

b) difference of terms

c) perfect square trinomials

d) difference of perfect squares

The answer is c) perfect square trinomials, for a perfect square trinomial is a trinomial that can be factored into a binomial multiplied to itself.

In the scenario of a perfect square trinomial, there will be 2 terms that'll be perfect squares. For example, in the trinomial x2 - 12x + 36, both x2 and 36 are perfect squares.

In this case, it is a special product formula because there's a specific formula for them - unlike the other answers.
