Suppose your SSN is 121-21-2121. How many other people could have the same SSN? SSN(x)= (x-a1)(x+a2)(x-a3)(x+a4) and so on..
What is a1, a2, a3,.... ?
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
Do you know Permutations?
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
i have to state one that would be? how can i find one that is equ to 121212121
Your SSN is unique but not your SSN polynomial
yeah I understand I have to find an SSN polynomial equal to that ssn
Oh no! Not this problem again. Askme, Your teacher is a sadist!
Social Security Number lol!
