8x^2-6x--

=(8x^2 +6x) + (-12x-9)

= 2x(4x+3) - 3(4x+3)

=(4x+3)(2x-3)

8x^2-6x-9
Factor
(4x+3)(2x-3) is your answer
-----------------------------------------
2 x 4 = 8 So put the factors of the equation (4,2)
(4x+3)(2x-3)
-----------------------------------------------------------
3 x 3 = 9 Put the factors again (3,3)
(4x+3)(2x-3)
