For the polynomial \(8 y^{4}-3 y^{2}+1\) (a) Is it a monomial, binomial, or trinomial? (b) What is its degree?

Short Answer

Expert verified
(a) Trinomial, (b) Degree 4.

Step by step solution

01

Identify the Number of Terms

The polynomial given is \(8 y^{4}-3 y^{2}+1\). Determine how many terms are in this polynomial. For this polynomial, the terms are \(8 y^{4}\), \(-3 y^{2}\), and \(1\). Thus, the polynomial has three terms.
02

Classify the Polynomial

Based on the number of terms identified, classify the polynomial. A monomial has one term, a binomial has two terms, and a trinomial has three terms. Since there are three terms, this polynomial is a trinomial.
03

Identify the Degree of Each Term

The degree of a term is the exponent of the variable in that term. For \(8 y^{4}\), the degree is 4. For \(-3 y^{2}\), the degree is 2. For the constant term \(1\), the degree is 0.
04

Determine the Degree of the Polynomial

The degree of a polynomial is the highest exponent of the variable in the polynomial. From the identified degrees, the highest is 4. Hence, the polynomial has a degree of 4.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Trinomial Definition
A trinomial is a special type of polynomial. A polynomial is an expression that consists of variables, coefficients, and non-negative integer exponents. They can be made up of multiple terms combined using addition or subtraction. The term 'trinomial' specifically describes a polynomial that contains exactly three terms.

For instance, in the polynomial given in the exercise, \(8y^4 - 3y^{2} + 1\), we can see that it contains three distinct terms: \(8y^4\), \(-3y^2\), and \(1\).

The presence of exactly three terms classifies the polynomial as a trinomial. This is why, in step 2 of the solution, the polynomial was classified as a trinomial.
Degree of Polynomial
When we talk about the degree of a polynomial, we are referring to the highest exponent of the variable in any of its terms. This tells us a lot about the polynomial’s behavior, especially for large values of the variable.

Each term in a polynomial can have its power or degree. For example, in the term \(8y^4\), the exponent is 4, so the degree of this term is 4.

Let's look at the terms in our example polynomial: \(8y^4 - 3y^2 + 1\):
  • \(8y^4\): Degree 4
  • \(-3y^2\): Degree 2
  • \(1\) (constant term): Degree 0

The highest degree among these terms is 4, which means the degree of the polynomial is 4.

Understanding the degree of a polynomial helps in many areas, including graphing and solving polynomial equations.
Terms in Polynomials
A polynomial is composed of several terms. Each term is a product of a constant coefficient and a variable raised to a non-negative integer power. For example, in the polynomial \(8y^4 - 3y^{2} + 1\):

  • \(8y^4\) is a term with coefficient 8 and variable \(y\) raised to the power 4
  • \(-3y^2\) is a term with coefficient -3 and variable \(y\) raised to the power 2
  • \(1\) is a constant term with a coefficient of 1 and a variable power of 0

Identifying individual terms in a polynomial is crucial because each term's degree and coefficient determine the polynomial's overall structure and properties.

Moreover, the nature of the terms (whether they include variables or are constants) plays a major role in the polynomial classification and degree analysis.
