Proved 2+2=5 :P

[Rajnish Kaushik 18]

2+2=4

=4-9/2+9/2

=square root of(4-9/2)²⁺9/2

=square root of(16-36+81/4)+9/2

=square root of(-20+81/4)+9/2

=square root of(25-45+81/4)+9/2

=square root of(5²-2*5*9/2+(9/2)²)-9/2

=square root of(5-9/2)²-9/2

=5-9/2+9/2

=5

Hence proved that 2+2=4

i have mistaken anywhere then please tell me!!!!

(-1/2)² = (1/2)² . However -1/2 ≠ 1/2.
