The next step is to identify which, if any, terms can be combined. Remember, only like terms — constant terms or terms with the same variable — can be combined.
- 3x + 14x + 7x^2 - 3x + 4x^2 + 4x
In this case, we have four x-terms and two x^2-terms. Both the x-terms and the x^2-terms can be combined, so to simplify the expression we will rearrange it according to the Commutative Property of Addition and then combine like terms.
