see first u have to split up the 2nd term so as to get 2 terms, the product of which wil be equal to the product of the 1st and 3rd term
8x^2 -14x+12x-21
8x^2+12 x -14x-21
4x(2x+3) -7(2x+3)
(4x-7)(2x+3)

(4x - 7) ( 2x + 3 )
if u break it down,
8x^2 +12x -14x - 21
8x^2 - 2x - 21
so the answer is
(4x - 7) (2x +3)

8x^2-2x-21=8x^2+12x-14x-21
4x(2x+3)-7(2x+3)=(2x+3)(4x-7)
