The next step in simplifying this expression is to identify which, if any, terms can be combined. Remember, only like terms — constant terms or terms with the same variable and the same exponent — can be combined.
7m - 8n^2+ 3n + 2n^2 - 4m+ 3n
We have three pairs of like terms: two m-terms, two n^2-terms, and two n-terms. To simplify the expression we will rearrange it according to the Commutative Property of Addition and then combine like terms.
