Answer: $(9x)^{2}-(7)^{2}=(9x-7)(9x+7)$

Step-by-step explanation:

1. By definition you have that the difference of squares is:

$a^{2}-b^{2}=(a+b)(a-b)$

2. Given the polynomial:

$81x^{2}-49$

You can identify that there are two terms whose signs are different and they are perfect squares.

3. Therefore, you have:

$81x^{2}-49=(9x)^{2}-(7)^{2}=(9x-7)(9x+7)$
