Study Notes
Classifying Polynomials
- Polynomial Types: Polynomials are categorized by both degree (highest exponent) and the number of terms.
- Monomial: A polynomial with one term, e.g., -2.
- Binomial: A polynomial with two terms, e.g., 3x + 9.
- Trinomial: A polynomial with three terms, e.g., x³ + 5x² - 3x.
Types of Polynomials by Degree
- Constant: Degree of zero, represented by a single value, e.g., 5.
- Linear: Degree of one, example includes 3x + 9 or simply x.
- Quadratic: Degree of two, e.g., 5x² - 3x + 7 or -x² - x.
- Cubic: Degree of three, represented by forms like -2x³ or x³ + 5x² - 3x.
- Sixth Degree Polynomial: Contains four terms, such as x⁶ + 3x³ - 2x + 1.
Polynomial Structure
- Leading Coefficient: The coefficient of the term with the highest exponent in standard form.
- Standard Form: Polynomials are written with terms arranged from highest to lowest exponent.
- Coefficient: The numerical factor in front of a variable, e.g., in -2x², -2 is the coefficient.
- Variable: A symbol used to represent an unknown quantity, commonly seen as x or y in expressions.
Additional Terminology
- Degree of a Term: Determined by the exponent on the variable; in 3x², the degree is 2.
- Degree of a Polynomial: Identified as the highest degree present among its terms.
- Term: A single mathematical expression that can be a number, variable, or a product of numbers and variables.
Summary of Example Polynomials
- Quadratic Trinomial: 5x² - 3x + 7
- Linear Binomial: 3x + 9
- Constant Monomial: -2
- Cubic Monomial: -2x³
- Quadratic Binomial: -x² - x
- Cubic Trinomial: x³ + 5x² - 3x
- Quadratic Monomial: 7y²
- Cubic Polynomial with Four Terms: 9x³ - 5x² + 6x - 1
These classifications facilitate the understanding and manipulation of polynomials in algebra.
