The first 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.
(4x^3+2x^2+1)+(3x^2+8x+2)Since no numbers and minus signs are preceding the parentheses, we can remove them.
4x^3 + 2x^2 + 1 + 3x^2+ 8x + 2
In this case, we have one x^3-term, two x^2-terms, one x-term, and two constants.
Both x^2-terms and constants can be combined, so to simplify the expression we will rearrange it according to the Commutative Property of Addition and then combine like terms.
