i also prove 2+2=5

here

we know that

0=0

-20 = -20 (the is no problem to know what that)

16-36 = 25-45 (we Can Write The no problem still)

(4^2)-2(4)(9/2)+{(9/2)}^2=(5^2)-2(5)(9/2)+{(9/2)}^2

(just open it with the formula of (a-b)^2 which is ballance both side)

(4-9/2)^2 = (5-9/2)^2

(close the third equestion as (a-b)^2)

taking squre root both side

4-9/2= 5-9/2

( after that -9/2 is cancell)

4=5

we can write that

2+2= 5

Have FUN
