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 = 4 12 1

= here x=12 and y=1

= - = - = - similarly 48 can also be written as

48 = 4 4 3

= here x=4 and y=3

= - = - = - 48 can also be written as

48 = 4 6 2

= here x=6 and y=2

= - = - = - Similarly for 64 = 4 16 1 = - 64 = 4 8 2 = - 64 = 4 4 4 = - Similarly we can do it for other multiples of 16.
