WebTheorem 18. Let f(x) be a monic polynomial in Z[x]. In other words, f(x) has integer coefficients and leading coefficient 1. Let p be a prime, and let n = degf. Then the congruence f(x) 0 (mod p) has at most n incongruent roots modulo p. Proof. If n = 0, then, since f(x) is monic, we have f(x) = 1 . In this case, f(x) has 0 WebLast month, I asked whether there is an efficient algorithm for finding the square root modulo a prime power here: Is there an efficient algorithm for finding a square root modulo a prime power?

Webwe have shown that if 13 is a quadratic residue modulo an odd prime p, the polynomial g has a root modulo any power p~. The same argument works if 17 or 221 is a quadratic residue modulo a prime p. For powers of 2 we note that 17 --- 32 mod 23 and work as above but Webobservations imply that all theorems proved for monic polynomials in this paper are also true for nonmonic polynomials. We conclude this section by recalling several elementary matters in the arithmetic of rational numbers (mod p). A fraction a/b (mod p) is defined for ptb as the unique solution x (mod p) of the congruence bx-a (mod p). The WebWe introduce a new natural family of polynomials in F p [X]. ... We also note that applying the Rational Root Theorem to f m, p (X) shows that -1 is the only rational number which yields a root f m, p for a fixed m and all p. ...

Weba is a quadratic non-residue modulo p. More generally, every quadratic polynomial over Z p can be written as (x + b)2 a for some a;b 2Z p, and such a polynomial is irreducible if and only if a is a quadratic non-residue. Thus there are exactly p(p 1) 2 irreducible quadratic polynomials over Z p, since there are p choices for b and (p 1)=2 ...
