Question

Which best describes the expression 12/a + 2a - 8?

a. monomial

b. binomial

c. trinomial

d. not a polynomial

Answer 1

The correct option is c. trinomial

Explanation:

If we want to answer the question, we need to know some terms.

A binomial expression is an expression which is formed by the sum or the subtraction of two terms (or two monomial).

For example :

`a+b` is a binomial expression

When we only have one term :

`b` is a monomial expression.

The expression :

`(12)/(a)+2a-8`

is formed by the sum and subtraction of three terms ⇒ It is called a trinomial expression.

And that's the correct answer.

We can also add that a polynomial expression is an expression which is formed by many monomial terms.

`5x^(6)+3x^(4)+3x^(3)-12x^(2)+x-5` is a polynomial expression.

The correct answer is c. trinomial
