Here we will work out the first problem step by step (click here):
1. Try Substitution:
2. Factor both the numerator and denominator:
Once factored, the numerator and the denominator showed that they have a common factor, (x-2). This factor was then cancelled out, leaving a simplified fraction.
Here is another example using factoring (click here):
Last example … (click here):
I did not find factoring to be too challenging. The only obstacle I came across when dealing with limits was remembering that factoring is an option. Don’t forget that there are multiple ways to solve the limit.
