Homework Statement
Prove that if F is a finite field then there is a quadratic polynomial in F[x] that is irreducible over F
Homework Equations
The Attempt at a Solution
To Prove:At least 1 Quadratic polynomial:Ax^2 +Bx +C not = P(x)Q(x)
I know that if P(x) is a polynomial of degree n over any field F, then P(x) = 0 has at most n distinct solutions.
Therefore a quadratic polynomial will have at least 2 zeros in any F.
But I don't what to do after that...
