Where my math wizards 🧙‍♂️ at??

Hey guys I was just doing some studying and on this problem, I believe the tutor is multiplying two binomials by one another. My question is, why didn’t he foil?

Update: is it because there’s no operation sign between the two? Would this be looked at as one term in each parentheses?

I know this isn’t a math app. I was just hoping I could get help.

Update #2.

It’s not pemdas, but it’s using distributive property. I’m trying to see why he didn’t use foil method.
