So for this question, we want to write this expression as the product of two. By normal's. This is a kind of an interesting one, because you would think, OK, you have X Triple seven X plus X. We could just make that extra call eight extra seven factor that way. But what they're trying to get you to do is to use that trick where you take two terms in the two terms, finds the, um, a normal factor for both of those and then factor like that. So we're gonna do is basically just do what they want us to do here. So we're gonna take our X squared me highlight. We have X squared and extra mes as our first pair and then our second barrel the seven Excell seven. Let's start with our expert plus X. If you break that down, in fact, or that we're going to get just X Times X plus one is pretty easy to see that one now for our seven x Class seven. It's pretty easy to see this one to. You're just going to get seven times X plus one. As you can see, there's that common X plus one here and very easily. You can write that answer, and it would be a plus here to write that answer as taking first experts one, then taking the coefficient so X in plus seven, and that would be your answer.
