Answer 2

Step-by-step explanation:

Probably the most common thing you will be doing with polynomials is "combining like terms". This is the process of adding together whatever terms you can, but not overdoing it by trying to add together terms that can't actually be combined. So which terms can be combined, and why?

Terms can be combined only if they have the exact same variable portion. And, by "exact same", I mean "the same variable(s), raised to the same power(s)".
