Answer 2

Answer: The correct option is (B)
`(2b+3)(2b-3).`

Step-by-step explanation: We are given to factorize the following expression :

`E=4b^2-9.`

We will be using the following factorization formula :

`a^2-b^2=(a+b)(a-b).`

The factorization is as follows :

`E\\\\=4b^2-9\\\\=(2b)^2-3^2\\\\=(2b+3)(2b-3).`

Thus, the required factored form is
`(2b+3)(2b-3).`

Option (B) is CORRECT.
