Exploring Adding and Subtracting Polynomials

This video tutorial covers simplifying polynomial expressions using addition and subtraction. It begins with an introduction to the steps involved, such as distributing signs and combining like terms. The tutorial then demonstrates how to handle subtraction in polynomials and provides advanced examples, including tricky problems. The video emphasizes writing expressions in standard form, starting with the greatest exponent.
