Answer:

B. (2x-5)(3x+1)

Step-by-step explanation:

Given expression is,

[tex]6x^2-13x-5[/tex]

By middle term splitting,

[tex]6x^2-(15-2)x-5[/tex]

[tex]6x^2-15x+2x-5[/tex]    ( By distributive property )

[tex]3x(2x-5)+1(2x-5)[/tex]

[tex](3x+1)(2x-5)[/tex]

[tex]\implies 6x^2-13x-5 = (3x+1)(2x-5)[/tex]

Hence, option B is correct.
