Here are the essential concepts you must grasp in order to answer the question correctly.
Polynomial Definition
A polynomial is an algebraic expression that consists of variables raised to non-negative integer powers and coefficients. It can include constants and can be expressed in the form of a sum of terms, where each term is a product of a coefficient and a variable raised to a power. Expressions that contain negative exponents, fractional exponents, or variables in the denominator are not considered polynomials.

Degree of a Polynomial
The degree of a polynomial is the highest power of the variable in the expression. For example, in the polynomial 3x^4 + 2x^2 + 1, the degree is 4 because the term with the highest exponent is x^4. The degree helps classify the polynomial and is crucial for understanding its behavior and graphing.

Types of Polynomials
Polynomials can be classified based on the number of terms they contain. A monomial has one term (e.g., 5x), a binomial has two terms (e.g., x + 3), and a trinomial has three terms (e.g., x^2 + 2x + 1). If a polynomial has more than three terms, it is simply referred to as a polynomial without a specific name. This classification aids in identifying the structure of the polynomial.
