Explain how to tell if two terms are alike. Show one pair of like terms that each contain at least two variables. Show how to add these like terms. Then show a second pair of terms that are NOT alike, but share some of the same variables. Explain why they are not alike.
Firstly, check if the two terms have the same variables. For example, 2kl + 3kl = 5kl are all like-terms. Add the coefficients and keep the same variables. Lastly, 3kp + 2lp are not like terms because they have don’t have the same exact variables.
