5718*5718 4135*4135 / 5718 + 4135
by using a^2-b^2= (a+b)(a-b)
so
(5718 + 4135)(5718- 4135)/ (5718+4135)
(5718 + 4135 ) will cancel out
so
(5718 - 4135) = 1583
by using a^2-b^2= (a+b)(a-b)
so
(5718 + 4135)(5718- 4135)/ (5718+4135)
(5718 + 4135 ) will cancel out
so
(5718 - 4135) = 1583

By using a^2-b^2= (a+b)(a-b)
Therefore, (5718+4135)(5718-4135)= (9853)(1583)
(9853)(1583)/5718+4135
= (9853)(1583)/9853
= 1583
Therefore, (5718+4135)(5718-4135)= (9853)(1583)
(9853)(1583)/5718+4135
= (9853)(1583)/9853
= 1583
