(2x - 4)(2x + 3) The key is to look for all the factor pairs of 12.
It is x^2 -x -12 is (x+3)(x-4) when factored
(x + 12)(x - 3)
(x - 5)(x + 12)
It is: (3x+4)(2x-3) when factored
(x - 12)(x + 12)
-22 - 12 = -8
(6x - 1)(6x - 1)
It is x^2 -13x +12 = (x-1)(x-12) when factored
The expression x2 + 1x - 12 can be factored out as (x - 3)(x + 4)
x2+2x-120 = (x+12)(x-10) when factored
(n - 4)(n - 12)
