Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression

Apply exponent rule: 
∵ 

Factor out common term 2y

We know that the Binomial is an expression that consists of two terms. Thus,
(4x²y²- 9) represents the binomial factor of 
We can further simplify by Factoring 4x²y² - 9: (2xy + 3) (2xy - 3)

Here:
(2xy + 3) and (2xy -3) are the binomial factors of
as each of them consists of two terms.
