I wanted to solve this without quadratic formula, discriminate, completing the square, or rational root theorem, or Eisensteins criterion

What do you think?

I think it should be fine because you explain every case. With a short look to your proof i dont see mistakes.

Here some suggestions :

  • irreductible is a statement for polynomials, (x^2+10x-3 for exemple) so you dont have to put =0 to make an equation. The statement would be : proof that x^2+10x-3=0 has no rationnal solutions.

  • it's a very long proof, in order to help People to understand it you can add sentences at the begining of each part

There are minor notation mistakes, everywhere that is says "element of Z[x]" or "element of Q[x]" is meant to be "element of irr(Z[x])" and such

Where is says let f, g=(3,1) it should say 3,-1

#

Also where it says gcd{fa, b}=/=1 when 3a^2/b = p| p is an integer

#

Is not quite right

#

Is should say gcd{fa, b}=/=1 or b=1 when 3a^2/b = p| p is an integer
