![]() ![]() It's another fancy word,īut it's just a thing that's multiplied, in this case, times the variable, which This is the thing that multiplies the variable to some power. Each of those terms are going to be made up of a coefficient. This thing you wrote in red, "this also has four terms." We have to put a few more rules for it to officially be a polynomial, especially a polynomial in one variable. Negative nine x squared the next term is 15x to the third and then the last term, maybe you could say theįourth term, is nine. This first polynomial, the first term is 10x to the seventh the second term is Terms, so lemme explain it, 'cause it'll help me explain You have to have nonnegative powers of your variable in each of the terms. So I think you mightīe sensing a rule here for what makes something a polynomial. To the third power plus nine, this would not be a polynomial. The negative seven power minus nine x squared plus 15x Replace the seventh power right over here with a That are not polynomials? Well, if I were to Seven y squared minus three y plus pi, that, too, would be a polynomial. Write the number six, that can officially beĬonsidered a polynomial. Even if I just have one number, even if I were to just Minus nine x squared plus 15x to the third plus nine. So, an example of a polynomial could be 10x to the seventh power And then we could write some, maybe, more formal rules for them. Of what are polynomials and what are not polynomials, ![]() We're gonna talk, in a little bit, about what a term really is. But in a mathematical context, it's really referring to many terms. The English language, referring to the notion ![]() The first part of this word, lemme underline it, we have poly. It'll start to make sense, especially when we start to This seems like a very complicated word, but if you break it down ![]()
