    Hello, when You are elaborating on the severeal possibilities of factoring the prime number 17, You are using the precondition that a and b are Natural numbers, but You didn't mention this precondition at the start.
    This is not a good example for mathematical argumentation in my opinion.
    Best regards.

    答案不只這些
    (2b+1)(2a+1) = 17 也可能是 (2b+1) = 0.5 (2a+1) =34 那答案就不一樣了

      Hallo,
      sorry, I do not understand.
      Please elaborate how You get from
      (2b+1)(2a+1) = 17 bzw.
      (2b+1) = 17/(2a+1)
      to
      0,5 (2a+1) =34 ?
      In general, if You habe one equation with two unkwnons, You cannot get to a unique solution with one number without making any other assumptions.
      Best regards

      (2b+1)(2a+1) = 17
      (2b+1) = 0.5 (2a+1) =34 { 0.5 x 34 = 17 }
      b= -0.25 a= 16.5 a+b=16.25 ....
      There are many different answers....
