Answer:
The correct option is c. trinomial
Step-by-step 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 :
[tex]a+b[/tex] is a binomial expression
When we only have one term :
[tex]b[/tex] is a monomial expression.
The expression :
[tex]\frac{12}{a}+2a-8[/tex]
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.
[tex]5x^{6}+3x^{4}+3x^{3}-12x^{2}+x-5[/tex] is a polynomial expression.
The correct answer is c. trinomial
