Question

Please answer !!!what is the product of the two binomials below?

Answer 1

Answer = D

Because:

(2A + 3B)(2A - 3B)
= 4A² - 6AB + 6AB - 9B²
= 4A² - 9B²

Answer 2

Answer: D. $4A^2-9B^2$

Step-by-step explanation:

Given expression : $(2A+3B)(2A-3B)$

We know that there is an identity of product of two binomials :-

$(x+y)(x-y)=x^2-y^2$

In the given expression , we have $x=2A\text{ and}\ y=3B$

Then by applying the above identity , we have

$(2A+3B)(2A-3B)=(2A)^2-(3B)^2\\\\=4A^2-9B^2$
