Step-by-step explanation:
Polynomials
A polynomial is a sum of terms in which all the exponents on the variables are whole numbers and no variables appear in the denominator or under a radical. The expressions
0.1
R
4
,
d
2
+
32
d
−
21
,
and
128
x
3
−
960
x
2
+
8000
are all examples of polynomials in one variable.
An algebraic expression consisting of one term of the form
c
x
n
,
where
c
is a constant and
n
is a whole number, is called a monomial. For example,
y
3
,
−
3
x
8
,
and
0.1
R
4
are monomials. A polynomial is just a sum of one or more monomials.
A polynomial with exactly two terms, such as
1
2
n
2
+

n
,
is called a binomial. A polynomial with exactly three terms, such as
d

32
d
−
21
or
128
x

−
960
x
2
+
8000
,
is called a trinomial. We have no special names for polynomials with more than three terms.
