Answer 2

B.
`(x-5)(x+3)`

Explanation:

We are given that an expression

`a^2-2x-15`

We have to find the binomial factors of the given expression.

`x^2-2x-15`

To find the factors of given expression we will use of middle term splitting factor method.

The given can be written as

`x^2-5x+3x-15`

`x(x-5)+3(x-5)`

Taking (x-5) common

`(x-5)(x+3)`

Hence, the binomial factors of given expression is given by

`(x-5)(x+3)`

Option B is true.
