You can make up your own or have your students create some! One that I have created is for factoring sum or difference of two cubes. x^3+y^3 = (x+y) then, we SOPPS the binomial to get the trinomial factor. S(quare) O(pposite sign) P(roduct) P(lus) S(quare) (x+y)(x^2 - xy + y^2) I will let you know if I remember any more. -Claudia, for the Teacher2Teacher service
