.
the difference of 2 numbers is 3. If the difference of their squares is 15, what is the sum of the numbers ?
~~~~~~~~~~~~~~~~~~~~~ 

 = 15  ====>  (x+y)*(x-y) = 15.


Now replace x-y by 3, according to the condition. You will get


3*(x+y) = 15  ===>  x + y =  = 5.


Answer.  x + y = 5.

Solved.

There is NO any need to solve quadratic equation.


            The solution should not be more complex than the problem requires.         (Einstein)
