2=1? Is it Possible???

Assume that a = b.

Because a = b, one can also assume that a^2 = ab.

Now we can see that following is possible: a^2 – b^2 = ab – b^2.

Now factor both sides: (a – b)(a + b) = b(a – b).

Now we can divide both sides by (a – b):

[(a – b)(a + b)]/(a - b) = [b(a – b)]/(a - b)

This cancels out the (a – b)’s in the problem, we are now left with:

a + b = b.

Earlier we defined a = b so now we can substitute a for b:

b + b = b which can also be written: 2b = b.

Now we divide both sides by b:

2b/b = b/b

Now all the b’s cancel leaving 2(1) = 1 which an also be written:

2 = 1

AMAZING!!!!!!!!!!!!

i'm doing work right now and i need to know quickly whether or not an object will sink or float if it's density is higher than the liquid. for example if the density of an egg is 1.03 g/ml will it sink or float in water if it is 1 g/ml. i need an answer quickly and this is due tomorrow!
