Open to the left column 2nd flap, and copy the following

onto it.

Go to the middle column second flap (We labeled it “Unfoil” ( )(

) at the bottom).

Copy the following onto the whole thing; I typed out top flap because it was too hard to read.

1.) List out factors of “a” (if a is negative, factors are opposite signs; otherwise same sign); these are FRONTS of factors2.) List out factors of c (if c is negative, factors are opposite

signs; otherwise same sign) these are LASTS of factors

3.) Look at the value of b, pick the pair of factors that add/subtract to get b.4.) Check by FOILing.

Go to the middle column third flap (We labeled it “Perfect

Square Trinomial” at the bottom).

Copy the following

? 2ab ?2 (2x)(5)

20x

? 2ab ?2 (2x)(5)
