Question Video: Identifying Monomials Mathematics • First Year of Preparatory School

Video Transcript

Chloe says that a monomial is an expression that contains a single variable, for example, 𝑥 plus 𝑥 squared. Is Chloe correct?

Unfortunately, no, Chloe is not correct. A monomial has one term, not one variable. And a term could be anywhere from 𝑥, 𝑥𝑦, 𝑥 squared 𝑦𝑧, four 𝑥𝑧, and so on. And notice there are no plus or minus signs anywhere. Once we add or subtract more terms, it’s no longer a monomial. So our answer is no, Chloe is not correct.
