Answer:
The correct option is 3.
Step-by-step explanation:
The given expression is
\(12x^2-4x-1\)
Write the middle term as -6x+2x.
\(12x^2-6x+2x-1\)
\((12x^2-6x)+(2x-1)\)
Taking out the greatest common factor from each parenthesis.
\(6x(2x-1)+1(2x-1)\)
Taking out the common factors.
\((2x-1)(6x+1)\)
It means (2x-1) and(6x+1) are two factors of the given expression. Therefore the correct option is 3.
