Factoring
Factoring is the breakdown of a mathematical term into smaller and simpler mathematical terms. When factoring for limits, some of the factors will cancel and you will not be left with 
.
Example:
However, if you factor the numerator it would result in 
The term 
would cancel on the top and the bottom leaving you with 
which can be found by substitution as 4.
