Hi;

See the following algebraic expression:

1/3(x + y + z)

It can be also written as: x/3 + y/3 + z/3

Or: (x + y + z)/3

Is this a monomial, binomial, trinomial or none of these?

Since it has 3 terms I would say trinomial.

If you distribute 1/3, the expression becomes x/3 + y/3 + z/3.

As you can see, three terms are formed.

This is a trinomial.

Hi;

See this algebraic expression:

4x +9x

It is a binomial.

When it is written 13x, it is a monomial.

Then what type of expression is this?

If there is a single variable the powers must be different.

Hi Amartyanil;

Supposing I said it is x + 3x + 4x + 5x, does it now have 4 terms? You should simplify first to 13x, where it is obviously a monomial.

Hi;

Do we count only the unlike terms and state them only as terms?

Basically + and - make more terms:

is still a monomial.
