And now for some facts you weren't aware of, 1=2 *with poll*

Can't divid.. crap someone beat me

haha yeah.

You can prove all sorts of nonesence when you divide by zero. Thats why you cant do it. Hiding the division by 0 in variables does not change the fact that you cant divide by it.

someone wrote that solution on his/her exam (and got a F 😉) and is now trying to justify it before he/she goes back and talks with his/her professor/teacher saying that he/she was right and the teacher/professor was wrong 😛

there's nothing wrong with it, it just didn't provide a solution.

It solved a proof is what it did. 😛

There is something wrong with it. He divides by zero.

You multiply an equality by zero, rearrange, and then divide the zero out - this is not a valid step.

 

[Molondo]

x(y - x) = (y + x)(y - x)

Since when can you divide by zero?

nope, you can arrange an equation hundreds of ways using all sorts of rules and methods, but sometimes the outcome doesn't provide a solution, as in this case. At this point (if you were actually trying to figure out what x = ) then you would have to give up and try a different plan of attack, beause 1 =/ 2

Prove my math is wrong then. 😛

You cannot divide both sides by (y - x) sine y - x = 0 according to original statement.

owned.

The good ol' divide by zero trick I learned in Pre-school and heard about in kindergarden. Keep up the good work!

i think it was his intention to have someone prove him wrong

 

[Evadman]

x(y - x) = (y + x)(y - x)

For those of you who slept through algebra, trust me, you can do that. We can now remove (y - x) from both sides to get

x = y + x

Uh, no.

 

[sandorski]

So 1 does not equal 2? Whoah, who'da thunk it?

 

[PurdueRy]

and to be a proof you have to do what you did backwards. Obviously multiplying both sides by zero is not an option

since 1=2

 

[linkgoron]

Isn't there division by 0 somewhere?

Ah y-x...

Uh, no.

Best answer yet.

simple. to the point.
:thumbsup:

umm, no.

I learned an interesting fact last night. I have little doubt that you're wondering how the hell I'm going to prove it. Okay...

Let's start with two variables, x and y. Let's assume that

x = y

Now we multiply both sides of the equation by y to get

xy = y²

Still true, so far so good. Now we subtract x² from both sides to get

xy - x² = y² - x²

which is still equal. Now here's the kinda tricky part. If we break down the equation into factors we get

x(y - x) = (y + x)(y - x)

For those of you who slept through algebra, trust me, you can do that. We can now remove (y - x) from both sides to get

x = y + x

But if you remember, just a moment ago we said that

x = y

meaning we can replace y with x, giving us

x = x + x

or

x = 2x

The it's just a matter of dividing both sides of the equation by x and we're left with

1 = 2

The world is flat.

you cant devide by ZERO

are you sure about that?

I once tried to divide by zero in a math exam by mistake, my paper burst into flames and I failed the course.

True story.

 

[tikwanleap]

ok ok, so you can't divide by zero.

There was another mistake in the original post.

x=2x doesn't imply 1=2.

It implies that x = 0.

I think someone pointed that out but i wanted to point it out again. 😛

Edit: Ah, that someone was SokaMoka.
