Here are some websites that might help clarify polynomial operations and factoring.
Polynomial addition and subtraction - http://math.about.com/library/blpoly.htm
Adding polynomials - http://www.regentsprep.org/rEGENTS/math/polyadd/sp_add.htm
Subtracting polynomials - http://www.regentsprep.org/rEGENTS/math/polyadd/sp_subt.htm
Multiplying polynomials - http://www.purplemath.com/modules/polymult.htm and http://www.jamesbrennan.org/algebra/polynomials/multiplication_of_polynomials.htm
Factoring polynomials - http://www.jamesbrennan.org/algebra/polynomials/factoring_polynomials.htm and http://www.purplemath.com/modules/simpfact.htm
In order for my students to earn extra credit, they must visit at least 2 of the sites and comment on both.
