Consider =1 for
-Provide two numerical examples illustrating validity.
Let n = 1






 




----------------------

Let n = 2






 








--------------------

-Show the statement is true in general.


Use FOIL:













---------------------

-What is the difference between using numerical values to show that
something is true and showing in general that something is true?
-When we use numerical values to show that something is true, we show it
ONLY for those particular numerical values and no others.

-What we show in general that something is true, we show it for all the
values stated, in this case for
