whoever gave you these questions is really mean. >.>

Some stuff in math is never used in the outside world, or in daily activities.  
Seriously, there are mathematicians who dont use a difference of two squares.  Ever.
How would a person that is not a mathematician use it in their life? other than because
you have to pass a math test about a difference of two squares. >.>

Say you want to multiply two numbers that are 2 units away (and you can't use a calculator). You can use the difference of squares rule to do this


Ex: multiply 23 and 25 or rewrite 23 as 24-1 and rewrite 25 as 24+1 to say that 

23*25 = (24-1)*(24+1)


You would then use the difference of squares to carry this out
