proof for 1=2 (1 Viewer)

[JamiL]

1=2 i will prove it
x-x=x-x
therefore: x(x-x)=(x-x)(x+x)
let y=(x-x)
therefore: yx = (x+x)y
Divide both side by y and you get
x=x+x
therefore: x=2x
therefore: 1=2
?????

any comments... 1 obvious;y can not equal to 2, any1 figure it out

u cant divide by 0

 

[*girl04*]

i think she just did

 

[JamiL]

darn u got it .... nice 2 no im a she considering i go 2 a guys school...
i rote let y=(x-x) so it wouldnt be as obvious...
but did i confuze u 4 a minute at least???

 

[clive]

no

 

[JamiL]

i had another1 that proved that all obtuse angles equaled 2 90*... but i 4got it

 

[velox]

took me about 35 seconds

 

[JamiL]

thats great it took me about 35mintues... lol

I dont get what those question marks are meant to be in the first line =P

* obviously isnt the sharpest tool in the shed *

 

[JamiL]

ah that actualy said x^2.. i used character map and it didn seem 2 work... oh well..
so it would read x^2 - x^2=x^2 - x^2

Seen one seen all.
Having seen the original, all variants officially take .2 seconds to figure.

This one's soooo old!

So, are you saying that there is no 'proof' of two unequal numbers being equal that you couldn't fault in .2 seconds?

There are many out there that don't involve division by 0

Of course, you can also times by 0, go to the power of 1/2, etc

Power of 1/2 - could you give me an example.

I'm currently looking for a geometric proof for 3 = 0

 

[Estel]

CM maybe I should say.... any proof that involves division by 0 can be spotted in .2 seconds...

2^1
=(2^2)^1/2
=4^1/2
=pos/neg 2
therefore 2=-2

 

[Zarathustra]

Why is that wrong, well obviously 2 doesn't equal -2 but there isn't some prohibition Thou shalt not take the square root - like there is with dividing by 0
So that could be done with any number?

x= (x^2)^0.5
=+/-x

Where's the mistake...
