Identifying like terms and unlike terms

 Like terms 

-terms have the same power ams and variables 

Example: 2y, -6y, 4y

                  2x², x²

                   x²y⁴, x²y⁴

Unlike terms 

-terms have powers and variables that differ 

Example: 2x, 2xy, y²

                  x³, x², x⁴

                 2y, xy
