**more information**

**Simplifying, then, means grouping the like terms. This is an important concept to understand, as it is the base for the addition and subtraction of polynomials.**

**Remember: You can only group like terms!**

*x*and 3 - NOT like terms - The second term has no variable4

*x*and 3*y -*NOT like terms - The second term now has a variable but it doesn't match the variable of the first term4

*x*and 3*x^2 -*NOT like terms - The second term now has the same variable, but the degree is different4

*x*and 3*x -*LIKE TERMS -Now the variables match and the degrees match**Here is another example I put together about how to simplify polynomials using algebra tiles:**
