The degree of the polynomial is the largest exponent of the variable in any term. Descending order means putting the term with the highest exponent first, and the lowest exponent last. In this case, look at the exponent on the variable r in each term. In the term -3r, the exponent on r is 1. In -5r2, the exponent on r is 2. In 2r4, the exponent on r is 4, and in -6, the exponent on r is 0. (This is -6r^0.) So in descending order, it's 2r4 - 5r2 - 3r - 6, and the degree is 4.
