Polynomial Operations and Concepts

This video tutorial covers the basics of adding and subtracting polynomials. It begins with an introduction to polynomials, explaining that they consist of multiple terms. The tutorial then demonstrates how to add polynomial terms by combining like terms, followed by a section on subtracting polynomials, emphasizing the importance of handling negative signs correctly. The video concludes with a method for distributing negative signs to simplify polynomial expressions.

What does the term 'polynomial' mean?

How do you handle a double negative in polynomial subtraction?

• Subtract it twice

• Ignore it

• Treat it as a positive

• Add it to the constant term

What is an alternative method for subtracting polynomials?
