Solving Limits by Rationalizing! (Calculus 1)

This video is a lesson on evaluating limits by rationalizing the function. Some limits cannot be solved by simple substitution, so we can use this to change the function into something we can solve.

Today's lesson is about a strategy we can use to solve limits known as rationalizing. This strategy is used when we have limits that become irrational when evaulated regularly. We can multiply our given function by the conjugate to make the function rational.
