Therefore, x has 3 as a factor.This is false for x=7 in the algebraic integers.Therefore, since the other statements are *not* all true, you are correct.===Subject: Re: JSH: Distributive property, math argument>...> The start is simple enough, where the x shown is in the ring of> algebraic integers.Let P(x) = 14706125 x^3 - 900375 x^2 - 17640 x + 1078>Why does it not work with my polynomial?>It's not your polynomial, of course, it's the *factorization* that you>use.>At the start of the post I point out that if f(x) = x + 3, and f(x)>has 3 as a factor, then x must have it as a factor as well.>That's *basic* Dik Winter, and if you accept that result, then at>least some things should be clear to you.>Notice I didn't mention a ring for x, as the statement is true,>without regard to the commutative ring.>yes, you did.>You said Consider f(x) = x+3, where x is an algebraic integer.> Yup, you're right.

We aren't arguing the distributive property, but something else entirely. You tend to make sloppy mistakes, like not checking all the conditions.
