How to identify like terms?
Identifying like terms is easy. Look for terms that have the same collection of letters, with the same exponent (or power) next to them. It is useful to know how to check for like terms: Check that the same variables (letters) appear in each of the terms. Check that the exponent of each variable is the same in each of the terms.
How to combine like terms in Algebra?
To combine like terms, you want to first reorder the terms so the powers are from highest to lowest. The like terms can be combined. That is, the terms with the same power can be combined. I'll write it with parenthesis first to show which ones can be combined. I hope that helps answer your question.

Can algebraic terms have the same variables?
Thus, from the above table, we can say that algebraic terms with the same variables are added to each other. The addition of certain terms was possible only because the variables in both these cases are the same even if the numerical coefficients are different which we can add as normal numbers and the variable factor remains as it is. Now, the terms which have the same variables are called like terms.
