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.
00:16
And the term is either a number, a variable, or a number times one or more variables.
00:24
And the words monomial, binomial, trinomial, those are names for certain types of polynomial.
00:31
Polynomials.
00:33
And so monomial is going to be 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.
00:47
And so in part a, we're given 8 minus 3x.
00:51
And our first step is to determine the number of terms we have in the polynomial.
00:58
And so our first term is going to be 8.
01:02
And our second term is 3x.
01:06
So this polynomial has two terms, making it a binomial.
01:14
In part b, we're given z squared minus 5 z minus 6, and our first term is going to be z squared...
