determine the following for: x08x08$x^2 - x^4 - 3x - 1$
a) determine the coefficient and the degree of each term.
\
b) the degree of the polynomial is \boxed{},
\quad the leading term is \boxed{},
\quad and the leading coefficient is \boxed{}.
Part (a)
For term \( x^2 \):
Step1: Find Coefficient
The coefficient is the numerical factor. For \( x^2 \), the coefficient is \( 1 \) (since \( x^2 = 1 \cdot x^2 \)).
Step2: Find Degree
The degree of a term with a single variable is the exponent of the variable. For \( x^2 \), the exponent is \( 2 \), so the degree is \( 2 \).
For term \( -x^4 \):
Step1: Find Coefficient
The coefficient is \( -1 \) (since \( -x^4 = -1 \cdot x^4 \)).
Step2: Find Degree
The exponent of \( x \) is \( 4 \), so the degree is \( 4 \).
For term \( -3x \):
Step1: Find Coefficient
The coefficient is \( -3 \) (since \( -3x = -3 \cdot x \)).
Step2: Find Degree
The exponent of \( x \) is \( 1 \) (since \( x = x^1 \)), so the degree is \( 1 \).
For term \( -1 \):
Step1: Find Coefficient
The coefficient is \( -1 \) (since \( -1 = -1 \cdot x^0 \), and \( x^0 = 1 \)).
Step2: Find Degree
The exponent of \( x \) (implicit) is \( 0 \), so the degree is \( 0 \).
Filling the table:
| Term | Coefficient | Degree |
|---|---|---|
| \( -x^4 \) | \( -1 \) | \( 4 \) |
| \( -3x \) | \( -3 \) | \( 1 \) |
| \( -1 \) | \( -1 \) | \( 0 \) |
Part (b)
Degree of the Polynomial:
The degree of a polynomial is the highest degree among its terms. From part (a), the highest degree is \( 4 \) (from the term \( -x^4 \)).
Leading Term:
The leading term is the term with the highest degree. The term with degree \( 4 \) is \( -x^4 \), so the leading term is \( -x^4 \).
Leading Coefficient:
The leading coefficient is the coefficient of the leading term. The leading term is \( -x^4 \), so its coefficient is \( -1 \).
