Homework Help: Can someone check my work? (Finding a common divisor T)

  1. Apr 24, 2012 #1
    1. The problem statement, all variables and given/known data

    Look at my work in the picture.

    2. Relevant equations



    3. The attempt at a solution

    I did a different method and I got 3 and 1 and still 1 is the only T that satisfies.

    Your photo is very difficult to read. Also, what is the statement you are trying to prove?

    I'm trying to find all values of natural numbers T that satisfy T l n^2-n+3 and T l n+1

    Take a look at this copy and the bottom is cut off. It is S={1}

    If n = 4, n + 1 = 5 and n^2 -n + 3 = 15, so 5 is in the set.

    Notice that I said "If n = 4".

    Here's your problem statement from post #3.
    There's no mention of "for every n."

    Yes it divides it but not for every n.
