Combining and Subtracting Polynomials

This video tutorial explains how to subtract polynomials by identifying and combining like terms. It covers the process of clearing parentheses, distributing negative signs, and changing the signs of terms. The tutorial provides multiple examples, including subtracting monomials, binomials, and trinomials, and emphasizes the importance of recognizing like terms and their coefficients. The video concludes with a summary and a promise of more examples in the next video.
