Monomial has only one term different

Binomial has only two terms different

Trinomial has three terms different

Let’s take some examples

###
**
28𝑥
**

It has only one term.

So its Monomial

###
**
2𝑥 − 3
**

It has two terms

So it is binomial

###
**
15𝑥y − 25y + 18
**

It has three terms

so it is trinomial

###
**
3𝑥 + 9x
**

3𝑥 + 9𝑥 = 12𝑥

So it is only term

∴ It is Monomial

###
**
2𝑥
**
**
+
**
**
3𝑥
**
**
+
**
**
8𝑥y
**

2𝑥 + 3𝑥 + 8𝑥y = 5𝑥 + 8𝑥y

So it has two terms

∴ It is Binomial

###
**
24xy − 25x
**
**
3
**
**
y
**

It has two terms

∴ It is binomial.

Now,

We learned that

Monomial has 1 term

Binomial has 2 terms

Trinomial has 3 terms

And

Polynomial has n terms

So, all monomials, binomial, trinomials are in fact polynomials.

So, all monomials, binomial, trinomials are in fact polynomials.
