Answer 2

Answer: the correct option is

(A)
`(13x+8)(13x-8).`

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

`E=169x^2-64~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

We will be using he following factorization formula :

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

From (i), we get

`E\\\\=169x^2-64\\\\=(13x)^2-8^2\\\\=(13x+8)(13x-8).`

Thus, the required factored form of the given expression is
`(13x+8)(13x-8).`

Option (A) is CORRECT.
