Study Notes

Classification of Polynomials

Monomial: An expression with a single term; e.g., -2.
Binomial: An expression containing two terms; e.g., 3x + 9.
Trinomial: An expression with three terms; e.g., 5x² - 3x + 7.
Polynomial: A monomial or the sum/difference of monomials.

Types of Polynomials by Degree

Constant: A polynomial with degree of zero; e.g., y = 5.
Linear: A polynomial with degree 1, represented in standard form (e.g., x).
Quadratic: A polynomial with degree 2; characterized by an x² term, e.g., -x² - x.
Cubic: A polynomial with degree 3; e.g., 9x³ - 5x² + 6x - 1.
Quartic: A polynomial with degree 4; e.g., xy³ + 5x³ - 3y³.
Quintic: A polynomial with degree 5; e.g., 7y²z³.
Sixth Degree: A polynomial with degree 6; e.g., x⁶ + 3x³ - 2x + 1.

Types of Polynomial Expressions

Quadratic Trinomial: An example is 5x² - 3x + 7.
Linear Binomial: An example is 3x + 9.
Cubic Monomial: An example is -2x³.
Quadratic Binomial: An example is -x² - x.
Quartic Trinomial: Example includes xy³ + 5x³ - 3y³.
Quintic Monomial: Example is 7y²z³.
Cubic Polynomial: An example is 9x³ - 5x² + 6x - 1.

Key Terms and Definitions

Coefficient: The numerical factor in front of a variable; for example, in 3x + 9, 3 is the coefficient.
Degree of a Polynomial: The highest degree of any term in the polynomial determines its classification.
Leading Coefficient: The coefficient of the term with the highest degree in standard form.
Standard Form of a Polynomial: A format where terms are arranged from highest to lowest exponent.

Summary of Concepts

Polynomials are classified based on the number of terms and the degree.
Understanding coefficients, degrees, and forms is essential for identifying and working with polynomials effectively.
