2x-1 is your answer. there is no addition in the problem so the secound 1 is eliminated and so is the 1st one because there is no 6.

Answer:

The correct option is 3.

Step-by-step explanation:

The given expression is

[tex]12x^2-4x-1[/tex]

Write the middle term as -6x+2x.

[tex]12x^2-6x+2x-1[/tex]

[tex](12x^2-6x)+(2x-1)[/tex]

Taking out the greatest common factor from each parenthesis.

[tex]6x(2x-1)+1(2x-1)[/tex]

Taking out the common factors.

[tex](2x-1)(6x+1)[/tex]

It means (2x-1) and(6x+1) are two factors of the given expression. Therefore the correct option is 3.
