Intro

- Hi, welcome to this question right here. So we're trying to write an equivalent expression. Equivalent expression means something that is exactly the same. They don't look the same, but they are the same. Okay, but you need to have seven terms, so there's multiple of different ways of doing this, actually infinity number of ways in doing this question. So I'm just going to do one example, it's your choice to come up with different answers, okay? The idea is the same. You need to get x square plus 2x plus three as your final answer, okay? 
I can quickly show you how the first way I'm going to do this is-- Let's say how many ways we're going to x square. Maybe I have two x square minus an x square. That will also give me one x square, right? 
Simple enough. What about the 2x? Well, I can say plus, let's change to another color. Plus four x and then minus 2x because these two guys right here will give me two x in total so that is my final answer. So far I got one, two, three, four, four terms now. So I need three more terms to satisfy the question, right? The question says seven terms in total. I need a three at the very end. So any ideas to get a three. Again, the number of the answers you're going to get for this question is like, I don't know how many. Okay, tons and tons. So how do you get a three at the very end? Well, let's try this way. How about let's plus a 10. So 10, let's say you subtract a two. I ran out of space. Minus two is eight. How do you get a three? Well, eight minus five. So try another five. Okay? 
So clearly if you just look at the colors, we&apos;ve got two yellows, two greens and three purples. So all together it's seven terms in total, and if you simplify these guys over here. I can show you really quickly again but you probably know the answer anyway. Two x square minus x square is x square. See, they're the same so far. Take the green one again, so the green one, we have 4x minus 2x. So it's plus 2x. What about the last type of the variables, not variables. The constants here, 10 minus two, minus five? The answer is three, and that's what happens. We&apos;ve got x square plus 2x and the minus three. These guys here, and these guys here are equivalent, the same, but they are-- Well, originally they look different but once you put it all together, they are the same. Okay? This is just to check and your final answer is not this. Your final answer is here, all these guys. Okay? One, two, three, four, five, six, seven, seven terms in total. All right, thanks for watching.

A polynomial may contain multiple terms. The variable terms have a coefficient and a <a href="[[glossary.html|{"keyword":"Variable"}]]">variable</a>. Terms with the same variables are called like terms, and they can be combined together. It allows us to write equivalent expressions of polynomials with more or less terms.
