Simplifying Polynomials and Like Terms

In this video tutorial, Joel explains how to simplify polynomials by adding and subtracting like terms. He begins by identifying like terms, focusing on terms with the largest exponents first. Joel demonstrates how to combine coefficients of like terms and rewrite the simplified polynomial. He also covers handling variables and constants separately. The video concludes with an invitation for feedback and contact information.
