Students will review:
In this course, you'll learn the answers to questions including:
- How can I solve polynomials of a degree greater than or equal to three?
- How do I add, subtract and multiply polynomials?
- What is quadratic form?
- How can I divide polynomials with long and synthetic division?
- How do I apply the remainder and factor theorems?
- What is the rational zeros theorem?
- What is the fundamental theorem of algebra?
1. 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.
2. Factoring Polynomials Using Quadratic Form: Steps, Rules & Examples
One of the best methods for factoring polynomials of a higher degree is using the quadratic form. Discover the steps and rules of how to change expressions into the quadratic form through examples provided in this lesson.
3. How to Divide Polynomials with Long Division
Polynomials can be divided using long division by dividing the first terms, multiplying the quotient by the divisor, subtracting it from the dividend, and continuously repeating the steps. Learn more about the steps for dividing polynomials with long division and why it is necessary to repeat the steps to complete the operation.
4. How to Use Synthetic Division to Divide Polynomials
Synthetic division is a shortened form of dividing polynomials by monomials that is shorter than using long division. Explore several examples of the synthetic division of polynomials and follow the correct order of steps to arrive at much simpler expressions.
5. 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.
6. 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.
7. 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.
8. 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.
