15n^2+6n^3-3n^3-5n^2-3n^2-5n^4
15n2+6n3-3n3-5n2-3n2-5n4

The red terms are like terms, which combine to +7n2

The blue terms are like terms, which combine to +3n3

The black term -5n4 is not like any other term.

In descending powers, we start with the black term, since it
has the largest exponent. Then the term with 3 exponent, and
finally the term with the 2 exponent

-5n4+3n3+7n2
