Question

find the product using suitable identities. (2a+3/b) (2a-3/b)​

Answer 1

Step-by-step explanation:

using the identity (a+b)(a-b)=a²- b²

(2a)² - (3/b)²

4a²-9/b²

hope it helps you

Answer 2

Answer:

This is in the form (a+b)(a-b)

(a+b)(a-) = a² - b²

Here, 2a is a and 3/b is b

So, (2a)² - (3/b)²

= 4a² - 9/(b²)
