Algebra 1: Adding and Subtracting Polynomials

This video tutorial covers the basics of adding and subtracting polynomials in Algebra 1. It explains how to identify like terms and perform operations on them, using examples to illustrate the process. The tutorial also addresses more complex problems, emphasizing the importance of the distributive property when subtracting polynomials. By the end, viewers should be comfortable with these operations and ready to tackle more advanced problems.

What is the first step in adding or subtracting polynomials?

• Combine all terms regardless of their variables.

• Divide the terms by their coefficients.

• Identify and combine like terms.

• Multiply the coefficients of the terms.
