Answer

$7(x+2)(x-1)$

Work Step by Step

$7x2+7x-14\longrightarrow$ 7 is a common factor. =$7(x^2+x-2)$ =$7(\ \ \ \ \ \ \ \ \ )(\ \ \ \ \ \ \ \ \ )$ =$7(x\ \ \ \ \ \ \ )(x\ \ \ \ \ \ \ )$ =$7(x+\ \ )(x-\ \ )$ The factors of -2 must have unlike signs. =$7(x+2)(x-1)$ 2 and -1 have a sum of 1 and a product of -2.
