# How to order a polynomial in descending powers of x? [duplicate]

This question already has an answer here:

This should be very simple, even silly If I ask this mathematica

 Expand [(x + 1) (x + 2) (x + 3)]


Mathematica delivers me well

 6 + 11 x + 6 x ^ 2 + x ^ 3


as achieving this result

x ^ 3 + 6 x 2 + 11 x +6

• expr = (x + 1) (x + 2) (x + 3); expr // Expand // TraditionalForm – Bob Hanlon Jun 12 '15 at 23:39

This works nicely:

PolynomialForm[(x + 1) (x + 2) (x + 3) // Expand, TraditionalOrder -> True]
x^3 + 6 x^2 + 11 x + 6


The problem with PolynomialForm[] is that it is merely a wrapper, like MatrixForm[] for matrices. So, this makes things display pretty, but it should not be given as input for further calculations. You can copy the output, however.
