SSN(x)= (x-a1)(x+a2)(x-a3)(x+a4) and so on..

Answer 1

What is a1, a2, a3,.... ?

Answer 2

they are the numbers of the SSN for example if the number is 121-21-2121
in the SSN(x)- (x-1)(x+2)(x-1)(x+2) and so on

Okay so you want a SSN such that SSN(x) = SSN(x')

Now your SSN is 121212121
4 2s and 5 1s and In total 9 numbers

Answer 4

Do you know Permutations?

Answer 5

barely sorry

Answer 6

Hmm I am not sure, Maybe
\[\Huge9_{P_{4}} + 9_{P_{5}}\]
\[\frac{9!}{5!} + \frac{9!}{4!}\]
\[ 9\times8\times7\times6 + 9\times8\times7\times6\times5\]
People can have same SSN polynomial as yours
