Complete the table by classifying the polynomials by degree and number of terms.

\begin{tabular}{|c|c|c|}
\hline Polynomial & Name Using Degree & Name Using Number of Terms \\
\hline [tex]$2x^2$[/tex] & & \\
\hline [tex]$-2$[/tex] & & \\
\hline [tex]$3x-9$[/tex] & & \\
\hline [tex]$-3x^2 - 6x + 9$[/tex] & & \\
\hline
\end{tabular}

Terms for classification:
- Exponential
- Constant
- Monomial
- Binomial
- Linear
- Trinomial
- Quadratic



Answer :

Let's classify each polynomial based on its degree and the number of terms:

1. [tex]\(2 x^2\)[/tex]:
- Degree: The highest power of [tex]\(x\)[/tex] is 2. Therefore, it is a quadratic polynomial.
- Number of Terms: There is only one term. Therefore, it is a monomial.

2. -2:
- Degree: There is no [tex]\(x\)[/tex] term. Therefore, it is a constant polynomial.
- Number of Terms: There is only one term. Therefore, it is a monomial.

3. [tex]\(3 x - 9\)[/tex]:
- Degree: The highest power of [tex]\(x\)[/tex] is 1. Therefore, it is a linear polynomial.
- Number of Terms: There are two terms. Therefore, it is a binomial.

4. [tex]\(-3 x^2 - 6 x + 9\)[/tex]:
- Degree: The highest power of [tex]\(x\)[/tex] is 2. Therefore, it is a quadratic polynomial.
- Number of Terms: There are three terms. Therefore, it is a trinomial.

Based on this classification, the completed table is:

[tex]\[ \begin{tabular}{|c|c|c|} \hline \text{Polynominal} & \begin{tabular}{c} \text{Name Using} \\ \text{Degree} \end{tabular} & \begin{tabular}{c} \text{Name Using} \\ \text{Number of Terms} \end{tabular} \\ \hline $2 x^2$ & quadratic & monomial \\ \hline -2 & constant & monomial \\ \hline $3 x-9$ & linear & binomial \\ \hline $-3 x^2-6 x+9$ & quadratic & trinomial \\ \hline \end{tabular} \][/tex]
