The expression has a degree of 2.
A trinomial has a degree of 3
Explanations:Let the two numbers be represented by a and b
The difference of the two squares is written as:
[tex]a^2-b^2^{}[/tex]The expression can also be expressed as:
[tex]a^2-b^2=\text{ (a - b)(a + b)}[/tex]This is a binomial because it has its highest degree as 2.
A trinomial means that the expression will have a degree of 3, and does not represent the description here
