Answer :

Let’s use algebra. starting with x,y, the square of the difference is = + - 2

the square of the sum is


= + + 2


what if we subtract the square of the difference from the square of the sum.


- = (+ + 2 - (+ - 2)


- =


writing this in reverse


= -


multiples of 16 are 16,32,48,64,80…..starting with 48


48 = 4121


= here x=12 and y=1


= -


= -


= -


similarly 48 can also be written as


48 = 443


= here x=4 and y=3


= -


= -


= -


48 can also be written as


48 = 462


= here x=6 and y=2


= -


= -


= -


Similarly for 64 = 4161 = -


64 = 482 = -


64 = 444 = -


Similarly we can do it for other multiples of 16.
