Can U Prove 3 = 2 ?

This seems to be an anomaly or whatever u call in mathematics.

See this illustration:

-6 = -6

9-15 = 4-10

adding 25/4 to both sides:

9-15+(25/4) = 4-10+(25/4 )

Changing the order

9+(25/4)-15 = 4+(25/4)-10

(this is just like : a square + b square - two a b = (a-b)square. )

Here a = 3, b=5/2 for L.H.S and a =2, b=5/2 for R.H.S.

So it can be expressed as follows:

(3-5/2)(3-5/ 2) = (2-5/2)(2-5/ 2)

Taking positive square root on both sides:

3 - 5/2 = 2 - 5/2

3 = 2

Error occurs in equating positive square roots on both sides!

3 - 5/2 = - (2 - 5/2) and

- (3 - 5/2) = 2 - 5/2
