mary an jim have tickets to a concert. mary`s ticket number is one less than jim`s ticket number. the product of their numbers is 812. what are the two numbers?
(x)(x-1) = 812
This is impossable, as an odd number added to an even number always yeilds an odd. the numbers would need to have 1/2 in them, tickets don't have those.
That said, you can devide 812 by 2, subtract 1/2 or .5 from one ticket number and add it to the other.
