Practice makes perfect
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 — can be combined.
(- 3) + 4x + 2 + 2x + 2x
In this case, we have three x-terms and two constant terms. Both the x-terms and constant 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.
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 — can be combined.
- 8x + 4 + (- 3)
In this case, we have one x-term and two constant terms. Only the constant terms can be combined, so to simplify the expression we will combine like terms.
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 — can be combined.
7x^2 + 3x + 4 + 7x^2 + 3x + 4
In this case, we have two x^2-terms, two x-terms, and two constant terms. Both the x^2-terms, x-terms and constant terms can be combined. Now, we can rearrange the expression according to the Commutative Property of Addition and then combine like terms.
We want to simplify the given expression.
5(x-4)
We can use the Distributive Property to get rid of the parentheses. This will also let us see the correct coefficients for any terms with variables.
