In this video, we demonstrate how to simplify a difference quotient of a radical function by multiplying by the conjugate to rationalize the numerator. From this, we compute the instantaneous rate of change of the function, aka, the derivative.

This is lecture 50 (part 4/4) of the lecture series offered by Dr. Andrew Misseldine for the course Math 1050 - College Algebra at Southern Utah University.

This lecture is based upon general college algebra curriculum and not based upon an individual textbook. With that said, this lecture series is influenced by many great college algebra textbook on the market, namely Sullivan's, Stewart's, OpenStax's, McKeague's, Stitz-Zeager's, and many others.
