The difference of two squares expression is (d) 25a^2-36b^6
<h3>How to determine the difference of two squares?</h3>
The difference of two squares is represented as:
x^2 - y^2
Where x and y are perfect square expressions.
From the list of options, we have:
25a^2-36b^6
The terms of the above expression are perfect squares
i.e.
25a^2 = (5a)^2
36b^6 = (6b^3)^2
Hence, the difference of two squares expression is (d) 25a^2-36b^6

We will use the FOIL method to solve this.
(7x-7)(x+1)
Multiply 7x by x. Then, multiply 7x by 1. Then, multiply -7 by x. Then, Multiply -7 by 1.

Now, we need to simplify by combining like terms.

If you look, -7x and 7x are gone. This is because they cancel each other out.
I hope this helped and maybe consider giving me brainliest :)
