What is the factored form of 16x2-16x-12

Find the GCF of 16 and 12 which is 4. Now the problem should be 4(4x^2-4x-3) . Now do the bottoms up method. 4 times -3 is -12. Now you have to find which numbers multiply to -12 and add up to -4. It would be -6 and 2. New problem is 4(x-6)(x+2) Now we can't forget to divide the two by the GCF which is 4. -6/4 can't be done so we put the 4 in front of the x. 4(4x-6). Now do the same to he other. (4x+2). Combine them now. 4(4x-6)(4x+2) . The problem now is that both these expressions can be simplified. Divide (4x-6) by 2 which is (2x -3). Divide (4x + 2) which is (2x + 1). Full answer to this question is 4(2x-3)(2x + 1).
