All of us know that 2+2= 4, not 5. But in this case, I will prove that 2+2=5. Read my complete articles to know how it is possible.
For this we will take
16-36 = 25-45
Now we will add 81/4 on both side then,
16-36+81/4 = 25-45+81/4
By using formula: a^2-2ab+b^2 = (a-b) ^2
(4)^2(9/2) ^2-2*4*9/2 = (5) ^2+ (9/2) ^2-2*5*9/2
(4-9/2)^2 = (5-9/2) ^2
Taking square root on both sides we get:
4 – 9/2 = 5 – 9/2
4 = 5 – 9/2 + 9/2
4 = 5
Hence it is proved that 4 = 5
Means it is proved 2+2=5 because 4=2+2
