Dividing Simple Polynomials and Examining Rational Expressions

The video explores whether polynomials are closed under division, demonstrating that the quotient of two polynomials is not always a polynomial. It reviews the concept of sets, focusing on polynomials and rational expressions. The video explains how to factor and simplify rational expressions, addresses common misunderstandings in polynomial division, and provides examples. It concludes with a discussion on closure, using a counterexample to show that polynomials are not closed under division.
