# Determine how many variations of binomials to even and to odd powers there are if the signs of x and of y may be positive or negative

This is in regards to practicing binomials to various powers using pascals triangle and now we have to determine if the placement of negative sings within the binomial affect the expansion.

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
