<PRE><B>Question 988737</B>
 Use expressions for even and odd integers to confirm the conjecture that the product of an even integer and an odd integer is an even integer. 
-------
Even:: 2x
Odd:: 2x+1
------
Product:: 2x(2x+1) = 4x^2 + 2x = 2(2x^2+x)
----
Since the product is a product of 2 and another integer,
the product is even.
