There are at least 4 problems with your code: - if you want polynomials, you need to declare x as a variable of a polynomial ring over K - the syntax "f(x) = something" is only intended for symbolic functions, in your case you should just use standard affectation "f = something" - implicit multiplication does not work A[i]x is an error you should write A[i]*x - the syntax of the for loop is wrong

Here is a corrected version

K.<a>=GF(2^3)
x = polygen(K)
for ai in K:
for aj in K:
f = x^2 + ai*x + aj
print f

• if you want polynomials, you need to declare x as a variable of a polynomial ring over K - K
• the syntax "f(x) = something" is only intended for symbolic functions, in your case you should just use standard affectation "f = something" - something"
• implicit multiplication does not work A[i]x is an error you should write A[i]*x - A[i]*x
• the syntax of the for loop is wrong
