SUMMARY

The discussion centers on the impossibility of factoring the polynomial x^5 + x + 1 using modulo arithmetic. A participant references the successful factorization of (x + 3)(x + 5) as x^2 + x + 1 mod 7, but concludes that reversing this process to factor x^5 + x + 1 is not feasible. The consensus is that certain polynomials do not yield to factorization in modular arithmetic.

How can I factor [tex]x^5+x+1[/tex] using modulo? I know, for example, I could write [tex](x+3)(x+5)[/tex] as [tex]x^2+x+1 mod7[/tex]. How can I go backwards with this?

Thanks.
