Problem
Two numbers are such that their difference, their sum, and their product are to one another as . The product of the two numbers is:
Solution
Set the two numbers as and
. Therefore,
, and
. Simplifying the first equation gives
. Substituting for
in the second equation gives
Solving yields
or
. Substituting
back into the first equation yields
which is false, so
is not valid and
