Answer:
<h2>Trinomial.</h2>
Step-by-step explanation:
When an algebraic expression has one term, we say that is monomial, because the prefix <em>mono </em>means one.
When it has two terms, we say that is binomial, because the prefix <em>bi </em>means two.
When it has three terms, we say that is trinomial, because the prefix <em>tri </em>means three.
When it has more than three terms, we just say that is <em>x</em>-term polynomial. For example, if it has six terms, we say that is six-term polynomial.
<em>Therefore, according to this, the given expression is trinomial, because it has three terms.</em>
