So we’re going to start with some like terms. Some of you may already know what like terms are so what are like terms.
Well like terms as it says the word like means similar terms like the word the terms that have similar endings or sorry the exact same endings.
So what I mean by this is I’ll give you an example like that. a 2a and negative a these are like terms because they’re all defined with a okay so that pronumeral is all a so that’s why they’re called like terms so if I add them up subtract them I can gather them together when I that’s the idea of like terms so if I give you another example b 4b and negative 2b these are also like terms because as you can see they all have b it’s not b squared.
It’s not b cubed it’s simply b so these are all like terms as well all right? Now these ones a squared 3a squared 5a squared these are also like terms hopefully you all know why because we all have a squared at the end okay so a squared is common that’s why they’re called like terms.
Now this time we have a b three a b negative four a b now these are also like terms because they end in a b all of them end in a b so they’re common a b is common so therefore that’s why they’re called like terms okay so it doesn’t just because they’re like terms doesn’t mean they only need one per numeral they can have couple they can have three four even five as long as they are the same okay then they’re called like terms so you get the idea don’t you.
