Answer:
B.\((x-5)(x+3)\)
Step-by-step 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.
