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)?
