Exploring Adding and Subtracting Polynomials

The video tutorial explains how to add and subtract polynomials by combining like terms. It provides examples of both operations, demonstrating the process of identifying and combining like terms. The tutorial also covers the method of changing signs when subtracting polynomials and presents different approaches to solve polynomial equations, including aligning like terms and distributing negative signs.

What is the first step in subtracting polynomials?

• Combine like terms directly

• Change all the signs of the polynomial being subtracted

• Divide the polynomials

• Multiply the polynomials
