What are the degree and leading coefficient of the polynomial?

[tex]\[ x^6 - 23x^2 - 20 - 9x^4 \][/tex]

Degree:

Leading coefficient:

Answer :

To determine the degree and leading coefficient of a polynomial, we need to look at the terms of the polynomial and organize them by their powers of [tex]\( x \)[/tex].

The given polynomial is:

[tex]\[ x^6 - 23x^2 - 20 - 9x^4 \][/tex]

Step 1: Rearrange the Terms

First, let's write the terms in order of decreasing powers of [tex]\( x \)[/tex]:

[tex]\[ x^6 - 9x^4 - 23x^2 - 20 \][/tex]

Step 2: Identify the Degree

The degree of a polynomial is the highest power of [tex]\( x \)[/tex] in the polynomial.

In this rearranged polynomial, the highest power of [tex]\( x \)[/tex] is [tex]\( 6 \)[/tex], which comes from the term [tex]\( x^6 \)[/tex].

So, the degree of the polynomial is [tex]\( 6 \)[/tex].

Step 3: Identify the Leading Coefficient

The leading coefficient is the coefficient of the term with the highest power of [tex]\( x \)[/tex].

In this case, the term with the highest power is [tex]\( x^6 \)[/tex], and its coefficient is [tex]\( 1 \)[/tex].

Thus, the leading coefficient is [tex]\( 1 \)[/tex].

Final Answer:

- Degree: [tex]\( 6 \)[/tex]
- Leading Coefficient: [tex]\( 1 \)[/tex]
