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.
