You have been asked in the past to make the question self-contained without relying on the title. You have also been asked to accept an answer if you find one useful. That said, I cannot understand what the question is. Maybe if you give an example it will be clear. –  Ross Millikan Nov 30 '11 at 0:47
    
What are $x$ and $y$? What are "variations of binomials"? How are you "practicing binomials"? Where are you placing negative signs? Etc, etc? –  Dimitrije Kostic Nov 30 '11 at 3:01
