What are Polynomials, Binomials, and Quadratics?

1. What are Polynomials, Binomials, and Quadratics?

Polynomials, binomials, and quadratics refer to the number of terms an expression has in math. Study the definition and the three restrictions of polynomials, as well as the definitions of binomials and quadratics.

How to Add, Subtract and Multiply Polynomials

2. How to Add, Subtract and Multiply Polynomials

Polynomials can be added, subtracted, and multiplied similarly to regular numbers once the variables have been organized. Learn the steps required to apply the principles of addition, subtraction, and multiplication to polynomials through a series of example problems.

Special Product: Definition & Formula

3. Special Product: Definition & Formula

Special products are the result of binomials being multiplied, or simplified further, and can be solved with ease using the FOIL method: first, outer, inner, last. Learn how to use these steps, and master binomial formulas by practicing below.

Pascal's Triangle: Definition and Use with Polynomials

4. Pascal's Triangle: Definition and Use with Polynomials

Pascal's triangle is a number pattern that identifies the coefficients of polynomial expansions. Learn the definition of Pascal's triangle and explore examples of its polynomial uses.

How to Use the Binomial Theorem to Expand a Binomial

5. How to Use the Binomial Theorem to Expand a Binomial

The binomial theorem can be used to determine the expanded form of a binomial multiplied by itself numerous times. Learn about the binomial theorem, understand the formula, explore Pascal's triangle, and learn how to expand a binomial.

Remainder Theorem & Factor Theorem: Definition & Examples

6. Remainder Theorem & Factor Theorem: Definition & Examples

In algebra, the remainder theorem is a formula used to find the remainder when dividing a polynomial by a linear polynomial, while the factor theorem links a polynomial's zeros and factors. Learn what this means by exploring the definitions and examples of both theorems.

Dividing Polynomials with Long and Synthetic Division: Practice Problems

7. Dividing Polynomials with Long and Synthetic Division: Practice Problems

Polynomials can be divided using both long and synthetic division, and so it is important to be comfortable using both. Learn the steps of both long and synthetic division of polynomials and use them to solve practice problems.

Factoring Polynomial Expressions

8. Factoring Polynomial Expressions

In algebra, it is important to know how to factor polynomial expressions. Learn some different methods of factoring polynomial expressions, including factoring quadratics, using the greatest common factor, and grouping, as well as how and when to use these methods.

Graphing Factorable Polynomial Functions

9. Graphing Factorable Polynomial Functions

Some polynomials can be factored. If a polynomial function is factorable then you can find the graph of the function by using the zeros and the end behavior.

Finding Rational Zeros Using the Rational Zeros Theorem & Synthetic Division

10. Finding Rational Zeros Using the Rational Zeros Theorem & Synthetic Division

A rational zero is a number that can be expressed as a fraction of two numbers, while an irrational zero has a decimal that is infinite and non-repeating. Learn how to use the rational zeros theorem and synthetic division, and explore the definitions and work examples to recognize rational zeros when they appear in polynomial functions.

Fundamental Theorem of Algebra: Explanation and Example

11. Fundamental Theorem of Algebra: Explanation and Example

The Fundamental Theorem of Algebra states that every polynomial function includes a minimum of one complex zero. Using an analogy based on bank fees, explore an explanation and examples of how to apply the theorem, and learn about imaginary, repeated, and complex solutions.

How Values Affect the Behavior of Polynomial Functions

12. How Values Affect the Behavior of Polynomial Functions

A polynomial function is a function that involves only the same category integer in an equation. Learn how specific values can determine a function's end behavior.

Basic Transformations of Polynomial Graphs

13. Basic Transformations of Polynomial Graphs

Polynomial graphs can be transformed in four basic ways: up and down, left and right, pinching and stretching, and flipping. Learn the definitions of polynomial functions and parent functions, and also how to analyze basic transformations of polynomial graphs.

Modeling with Polynomial Functions

14. Modeling with Polynomial Functions

Modeling real-world phenomena with a function is an extremely useful tool to have at our disposal. This lesson will explain how to model a given set of data points with polynomial functions using the method of finite differences.
