x^2  - y^2  = (x + y) (x - y)

 

We need   to have   (52)(48)

 

It's obvious that x must be < 52....because,if not, ...... y is positive.... and adding them together would produce  more than 52

 

So x must either be  50 or 48

 

Notice that if x  = 50 and y  = 2, we have

 

(50 + 2)  (50 - 2)  =

 

(52) (48)   !!!!

 

 

cool cool cool
