Boundedness Theorem Explained: Finding Upper & Lower Bounds of Polynomial Zeros with Example 4

Want to know how to fence in the real zeros of a polynomial?
The Boundedness Theorem helps you do just that — using synthetic division!
In this quick and clear lesson, Dr. Terri J. Speights from Math Exam Prep: Study on the Go! shows you how to:
✅ Use synthetic division to test upper and lower bounds
✅ Identify whether a number is a valid bound based on the signs
✅ Understand what it means when signs are all positive or alternate
✅ Narrow down your possible real solutions for faster solving
Perfect for Algebra 2, College Algebra, or anyone preparing for an exam!
