Simplifying Rational Expressions and Finding Undefined Values

Miacademy & MiaPrep Learning Channel

This video serves as a comprehensive algebra lesson on simplifying rational expressions, a core concept in high school mathematics. It breaks down the process into two main components: identifying values for which an expression is undefined (domain restrictions) and simplifying the expression itself by canceling common factors. The video progresses from simple, already-factored examples to more complex problems requiring polynomial factoring, including strategies for handling negative signs and factoring trinomials.
