Which of the following is equivalent to the expression above? Alright? To be honest, that looks a little daunting. But you just need to keep in mind one thing, and then that'll make it pretty straightforward. What is that one thing? You got to remember?

All right, cool. So the thing is, we want to combine like terms, not anything else. So whenever I see an x squared y, I want to combine it with another x squared y, regardless of the coefficient in front of it. So where do I see that? I see that right here with a negative x squared y. So I would want to combine these two.

So essentially, this whole question is just giving you an exercise in simplifying this entire concept here. So x squared y is going to combine with an x squared y. All right, what's next? Three y squared. So what else do you see three y squared point to it? You see it?

Yes, right there, three y squared. So we want to combine y squared with a Y squared. And what's next? five x, y squared. So where do we see another x y squared? We see it right here.

We want to combine that. Now one more thing to be careful about. Yeah, you know, this this negative right here, we want to distribute this negative and make sure not to leave it outside, outside the parentheses distribute that, but don't do anything else before you distribute that. Okay. So once you distributed it, let's actually combine them. So we got x squared y.

Now plus x squared y since we distributed that negative, okay, what's that going to give us? two x squared y. Okay, you see what I did with it? All right, don't sleep on me. All right. Next, we got three y squared, negative three y squared, because we have that minus sign right there.

And who is he going to combine with now with the plus three y squared. And you probably already thinking about this. It is just you're good. And we can combine this one more time. You can do the five x squared with the three x y squared. But look at this Watch.

Watch this. I know that my answer should have something with an x squared y. So let me take a quick license answers. I have an x squared y squared. Nope. x y squared, y squared?

Absolutely not. So it could be C. And it could be D because I have an x squared y and I have an x squared. Well, excellent. But then from our guys, the three y squared plus the three y squared, I see that I get a zero I should not have a y squared of my answer. Where do I see a y squared? Oh, I see it right here.

That's not it's not gonna work. Sorry about that. So it's not D and our answer is going to be C and you just saved yourself a couple more seconds and probably large headache trying to do it. The last part
