    So the social security polynomial : ssn(x)= (x-a1)(x+a2)(X-a3) (x+a4).. *and so on* Suppose your SS# is 121-21-2121. How many other people could have the same polynomial?

    So everyone recieved a unique code that they called their "social security number" they had to plug that code into a equation called SSN(x)=(x-a1)(x+a2)(x-a3) and so on.. then a few questions were asked : a) suppose you have a SS number in which the digits a1,a3,a5,a7 are all different (accroding to the equation they are all negative) and a2,a4,a6,a8 are all different (positive) Give two SS numbers that have the same ssn(x) polynomial. and then this question b) Suppose your SSN is 121-21-2121. What would your polynomial be - It would be ssn(x)=(x-1)(x+2)(x-1)(x+2) and so on, how many other people could have the same SSN(X)?

    Is this question from a pre-calculus textbook? Is there a textbook associated with the course?

    No, it was a project. The full handout is posted online if you want a full look

    I don't think I like this project. But this particular question seems to be about combinations and permutations

    How many different ways can you write 121-21-2121 ?

    hmm - I know its plenty. Not sure how to approch this with a formula rather than writing it all out
