    Good catch on defn of reducible- what is even cooler is that you and the class caught it! I always appreciated those moments when I taught. You make very few errors and your class is following.

      Thanks! It does feel like I'm making more and more errors as the years go by though!

    I was in high school probably around when you were and the rational root test was indeed in my text book. I believe Descartes rule of signs was in that same unit. Really enjoying your lectures.

      Thanks, glad you are enjoying the lectures. What you said reminds me that I was actually looking over my high school "math analysis" notes a year or two ago and I couldn't believe what I saw. My high school teacher actually taught us basic elements of both abstract algebra and real analysis. I hadn't remembered that he had done that. There was stuff in there about groups, rings, and fields and then there was also stuff about epsilon-delta proofs. I guess I just assumed at the time that it was part of the standard curriculum.

    In mod p irreducibility test how to choos prime p??

    • @billkinneymath
      @billkinneymath  5 лет назад +1

      Usually it is best to just try low values of p and see if they work or not. Sometimes, however, no value of p works.
