Factoring Polynomial is a chapter that comes after Radical chapter. It shares the same law as the Radical chapter. However, in this chapter we are breaking the radical forms by factoring it. Most of the questions consist of factoring trinomial, determining if a given binomial is a factor of a given trinomial and etc…  Rationalizing, conjugating, and foiling is used in this chapter.

For example,

X²-4 = ( X+2)( X-2)

In this equation, I basically used the method of conjugating and rationalizing by cancelling positive and negative 2x as I know that X times 2 is 2X and X times -2 is -2X which cancels out when added together.
