Which products result in a difference of squares or a perfect square trinomial? check all that apply. (5x + 3)(5x – 3) (7x + 4)(7x + 4) (2x + 1)(x + 2) (4x – 6)(x + 8) (x – 9)(x – 9) (–3x – 6)(–3x + 6)

In this question, we have to find all the products which result in a difference of perfect squares .

The formula of the difference between squares is

In the first option, we have

Which is of the form of difference of two squares. And similarly , the last option is also in the form of difference of two squares .

And for perfect squares, we have same factor twice in b and e, so for that b and e are the correct options .

So out of the given options, correct options are a,b,e and f .
