Let’s use algebra. starting with x,y, the square of the difference is 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 = - for example, 24= 4 = here x=6 and y=1

= - = - = 72 – 52

similarly 24 can also be written as

24 = 4 3 2

= here x=3 and y=2

= - = - = 52 – 12

so 24 =72 – 52= 52 – 12

other multiple of 8,

32 = 92 – 72 = 62 – 22

32 = 4 8 1

= here x=8 and y=1

= - = - = 92 – 72

similarly 32 can also be written as

32 = 4 4 2

= here x=4 and y=2

= - = - 32 = 92 – 72 = 62 – 22
