arrange the terms in descending order.
5  4x2 + x3  6x

Descending order means the term with the highest power (in this case 3) goes first then the term with the next highest power( 2) and then the x and then the constant.
Be sure to bring the negative signs along with the terms.

can you give an example

sure: how about
x^3  4x^2  6x + 5


so how would you work that out. i have the same kinda problem.

You are done. All you have to do is put them in descending order. You do this by looking at the exponents. You can't add them because they are no like terms.
You can add 6 x + 7x = 13x
You can add 6x^2 +7x^2 = 13x^2
You can not add 6x^2 + 7x
