2+2=4
it can be written as 4-(9/2)+9/2
= √(4-9/2)² + 9/2
= √16-2×4×(9/2)² +9/2
= √-20+(9/2)² +9/2
= √25-45+(9/2)² +9/2
= √5²-2×5×9/2 +(9/2)²
= √(5-9/2)² +9/2
= 5+9/2-9/2
= 5
Hence it is proved.

√(4-9/2)² from this u didnt get √16-2×4×(9/2)²

as 4-4 =10-10
2^2-2^2=2*5-2*5
(2-2)*(2+2)=5*(2-2)
simplifying both sides with (2-2)
ans becomes 2+2=5
note:--this is practically we cant do as w e cant cancel (2-2) as it becomes zero
due to this one of the ans can be cancel
2^2-2^2=2*5-2*5
(2-2)*(2+2)=5*(2-2)
