[?] Get Polynomial printout of -x +1 as -x +1 and not 1- x?

[klauspeterneuendorf]

Is there any way to have as polynomial output for polynomials in one variable always ordered polynomials from larger exponents to the constant as last part. I know TraditionalForm but it gives not the desired result for e.g. -x+1. This gives always the output as 1-x.

Something similar was discussed a few month ago in the thread: “Get polynomials in TraditionalForm to be ordered in descending order?”

[?] Get polynomials in TraditionalForm to be ordered in descending order?

I would like polynomials in TraditionalForm to be ordered in descending order of degrees. All the polynomials that I am dealing with are in one variable. For instance, I have -5x+3. TraditionalForm outputs 3-5x. I found an article HERE that talks about a solution, but I can’t get that solution to work. It says to do this: poly=-5x+3; MonomialList[poly, x]; poly // TraditionalForm But the output I’m getting is still 3-5x. What am I doing wrong? Thanks in advance, Mark Greenberg

You may adapt those techniques for your problem.

Thanks for the hint, Gianluca. I changed the wonderful

nicePolynomial[poly_,x_]

to

nicePolynomial[poly_Plus, x_]

and added as second definition

nicePolynomial[poly_, x _] := poly

and now a single monomial is displayed perfect also.
