i) ii) i) ii) Construct a field with 9 elements. Determine the irreducible polynomial satisfied by each element of the field in (i). The field is F,, the splitting field of x2-x, over F₂. Now x' - x = x(x-1)(x² + x +...+x+1) = x(x − 1)(x-2)(x² +1)(x² − x − 1)(x²+x-1) as a product of irreducible polynomials over Z,. how do we this get If œ is a root of x² +1 over Z3, then {1, α) is an F-basis of F₂. lequest So F, = {0, 1, 2, α, 2a, 1+ α, 1+2a, 2+α, 2+2α). expan this step 0, 1, 2 satisfy x,x-1, x-2, respectively. a, 2a satisfy x² +1, 1+ α, 1+ 2a satisfy x²+x-1 2+α, 2+2a satisfy x²-x-1.
