(1 point)
determine the following for: (-2x^8)
a) determine the coefficient and the degree of each term.
| term | coefficient | degree |
|---|---|---|
| (0x^7) | (square) | (square) |
b) the degree of the polynomial is (square),
the leading term is (square),
and the leading coefficient is (square).
note:
Part a)
For the term \(-2x^8\):
Step1: Find the coefficient
The coefficient of a term is the numerical factor. For \(-2x^8\), the numerical factor is \(-2\), so the coefficient is \(-2\).
Step2: Find the degree
The degree of a term with a single variable \(x\) is the exponent of \(x\). For \(-2x^8\), the exponent of \(x\) is \(8\), so the degree is \(8\).
For the term \(0x^7\):
Step1: Find the coefficient
The numerical factor here is \(0\), so the coefficient is \(0\).
Step2: Find the degree
The exponent of \(x\) is \(7\), but since the coefficient is \(0\), the term is essentially \(0\). However, following the definition, the degree of \(0x^7\) (as a term) is \(7\) (but note that a term with coefficient \(0\) doesn't contribute to the polynomial's degree).
Part b)
Step1: Degree of the polynomial
The degree of a polynomial is the highest degree of its non - zero terms. The non - zero term here is \(-2x^8\) with degree \(8\), so the degree of the polynomial is \(8\).
Step2: Leading term
The leading term of a polynomial is the term with the highest degree. Here, the term with the highest degree is \(-2x^8\), so the leading term is \(-2x^8\).
Step3: Leading coefficient
The leading coefficient is the coefficient of the leading term. For the leading term \(-2x^8\), the coefficient is \(-2\), so the leading coefficient is \(-2\).
Filling the table for part a)
| Term | Coefficient | Degree |
|---|---|---|
| \(0x^7\) | \(0\) | \(7\) |
