----------------------------------
The FOIL process results in a trinomial when the "O" and the "I"
products are "like" terms and can be combined.
-----------------------------------------
The inverse operation takes a middle term of a trinomial and breaks
it into two terms that allow for common factorization.
-------------------------------------------
Example: 2x^2 + 7x + 6
AC = 12
B = 7
---------
Think of 2 numbers whose product is AC and whose sum is B
The numbers are 3 and 4.
Break the middle term into 3x+4x then find a common factor as follows:
----------------
2x^2 + 3x + 4x + 6
x(2x+3) + 2(x+3)
(x+3)(x+2)
