<PRE><B>Question 271312</B>
Using Reverse Foil

Factor out the negative
6x^2+13x-28

It is really trial and error to find what times what will give you 6x^2.
You can try 1x and 6x, and 2x and 3x.
I chose:
(2x___)(3x____)
Next, figure out what multiplied by each other will give you 28 but added will give you 13 keeping in mind that you have the 3x and 2x to multiply using FOIL.
(2x-7)(3x+4)</PRE>
