2x^2+6x16 and 14x^23x2

12th grade math  PsyDAG, Monday, September 6, 2010 at 8:47pm
What factors does 14 have that can be combined with factors of 2 to add/subtract to get the middle
value?
14x^23x2 = (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)
