In this problem, we're being asked to identify any pairs of like terms.
00:04
Well, let's start by talking about what like terms are.
00:07
Life terms have to be two terms to have the same variable along with the same exponent.
00:12
So, for example, 9a and a squared would not be considered like terms, because a squared has an exponent of two.
00:20
And for this 9a term, the a's exponent is one.
00:23
So because they are not the same exponent, those are not like terms.
00:27
So let's see if we can identify any pairs of like terms.
00:30
Well, 9a doesn't have a like term because no upper term has just an a for a variable.
00:36
A squared doesn't have a like term because no upper term has a squared...
