$6(x^2+2x-1)$
$6x2+12x-6\longrightarrow$ 6 is a common factor. =$6(x^2+2x-1)$ =$6(\ \ \ \ \ \ \ \ \ )(\ \ \ \ \ \ \ \ \ )$ =$6(x\ \ \ \ \ \ \ )(x\ \ \ \ \ \ \ )$ =$6(x+\ \ )(x-\ \ )$ The factors of -1 must have unlike signs. =There are no 2 numbers that have a sum of 2 and a product of -1 so no further factoring is possible.
