In this problem, we're asked to determine if each of the following polynomials is a monomial, a binomial, a trinomial, or another polynomial.
00:10
And a polynomial is a mathematical expression made up of one or more terms, and a term is a number, a variable, or a number times one or more variables.
00:22
And the words monomial, binomial, trinomial, those are names for specific types of polynomials.
00:33
And so a monomial is a polynomial made up of one term.
00:38
A binomial is a polynomial made up of two terms.
00:42
And a trinomial is a polynomial made up of three terms.
00:46
And so in part a, we're given 11 y squared.
00:50
And our first step is to determine the number of terms in the polynomial.
00:56
And so a term can be a number times a variable.
01:01
And so this is just one term, making this a monomio.
01:11
In part b, we have negative 73.
01:15
And a number can also be a term all by itself...
