**PsyDAG**, Monday, September 6, 2010 at 8:47pmWhat factors does 14 have that can be combined with factors of -2 to add/subtract to get the middle

value?

14x^2-3x-2 = (7x + 2)(2x - 1)

I cannot find the factors for 2x^2 + 6x - 16. Are you sure you don't have a typo?

x^2 + 6x - 16 = (x + 8)(x -2)
