(68)²-(42)²/26
By (a+b)²=a²+2ab+b²
In Condition 1st
(68)²= 6²+2×6×8+8²
= 36+96+64
(Note::: Don't Add These Values.We need to Sum the Carry on Next term and then to second next)
= Here 6 Is Carry to 96 we get 102
and 10 is Carry to 36
So we get
== 4624
Condition No. 02
Applied The Same Formulae on (42)²
We get 1764
4624-1764/26
