how do you factor 16x^2-4x-6?

OpenStudy (anonymous):

you try to find two numbers that multiply to c (6) and two that add to b (4)

OpenStudy (campbell_st):

take 2 out as a common factor leaving \[2(8x^2 - 2x - 3)\] multiply 8 and -3 then find the factors that add to -2 then you can substitute into binomials \[\frac{2(8x + factor1)(8x + factor 2)}{8}\] cancel common factors from the numerator and denominator for the answer

yep that's wat i was going to say
