Understanding Division and Functions

This video tutorial explains how to divide two functions, f(x) and g(x), using an example where f(x) = 5x - 10 and g(x) = x - 2. The process involves simplifying the quotient by canceling common terms, resulting in a simplified answer of 5. The video also highlights the importance of considering undefined conditions, such as when x equals 2, which would make the denominator zero and the expression undefined.
