2=3 !

Let, 4 – 10  = 9 – 15

Add  in both sides then we get

4 – 10 +  = 9 – 15 +

(2)² – 2.2.+ (  )²  = (3)² – 2.3. + (  ) ² 

( 2 –  )^{2 =}  ( 3 –  )²

   ⁼ 

^{2 –   ₌ 3 –} 

Omitting  from both sides we get

2 = 3

My dear friends, I have done a mistake here. Have you got the mistake ?

 Negative numbers ( 2 –   ) have no simple square root
