Instructions: Classify the expressions by the number of terms. x2+3x+9𝑥2+3𝑥+9 6xy6𝑥𝑦

To classify the given expressions by the number of terms, we will analyze each expression separately.

1. Identify the Expressions

   • Expression 1: $x^2 + 3x + 9$
   • Expression 2: $6xy$

2. Count the Terms

   • For Expression 1:

     • The terms are $x^2$, $3x$, and $9$.
     • Therefore, there are 3 terms in this expression.

   • For Expression 2:

     • There is only one term, $6xy$.
     • Therefore, there is 1 term in this expression.

3. Classify the Expressions

   • Expression 1 $x^2 + 3x + 9$ has 3 terms (trinomials).
   • Expression 2 $6xy$ has 1 term (monomial).

Final Answer

• $x^2 + 3x + 9$: 3 terms (Trinomial)
• $6xy$: 1 term (Monomial)
