**L.Bianchessi**, Tuesday, February 28, 2012 at 4:42amExample--Difference of squares:

(x^2 + 5x-6) = (x+6)(x-1)

1. Write an x in both parenthesis

2. Find factors of 6. (6x1 or 3x2)

3. The inner (6x) plus the outer (-1x) should equal the middle term 5x

Or you could foil.

Trinomial:

(a+b)(a^2-ab+b^2)

(a-b)(a^2+ab+b^2)

Something like that. You can just look it up on Google. They have many examples.
