See explanation.

To write a polynomial in standard form you have to order its terms by decreasing powers of the unknown.

Here it will be:

#x^3+5x-3#

In this form you can say that:

It is a trinomial because itis a sum of 3 terms
The polynomial's degree is #3# - it is the highest power of the unknown with non-zero coefficient.
