Find the mistake :)

[Chickenrunnn]

Hey there !

Here is a (very) easy enigma Find out the problem xD

We firstly fix :
X=1 and by definition, X = X (Don't tell me you don't understand ._.)
<=> X² = X² (square)
<=> X² - X² = X² - X² (subtract X²)
<=> X(X - X) = (X + X)(X - X) (Factorize, Note that a²-a²=a(a-a), and that a²-b²=(a+b)(a-b))
<=> X = X + X (Simplify)
<=> X = 2 X (addition)
<=> 1 = 2 (because X = 1)

1=2 ?? OMGG .____.

If you can't find the reason why it is buggy, click on the spoiler

 

The problem comes from those 2 lines :
<=> X(X - X) = (X + X)(X - X) (Factorize)
<=> X = X + X (Simplify)

Indeed, you simplify dividing by (X-X), which is equal to zero, which is IMPOSSIBLE

Hehe
Hope you liked x)

What IS ALL THAT ALIEN LANGUAGE?!?
this better not be someone's math homework...

If I see this right X+X doesnt simplify to X (unless X was 0)

I don't know if X (X - X) = (X + X) (X - X) o_O?

Because one side is x² - x ² while the other is 2x...

[ultimaga95]

I missed the first line but i got the second line right. The only way you can get 2X I think is by doing X*X, not X+X. Right?

[DocDoBig]

Nubs, come back when you play with three-dimensional vectors and integral calculation.

^This is what Docs have OF COURSE to know .

[asimauara]

X=1 not 2 thats where the mistake is

[Delphina]

Ok I was lost after:
X=1 and by definition, X = X .......

[Revealing]

I was lost after hey I'm like wth lemme tell teacher this

You got it right

I don't know if X (X - X) = (X + X) (X - X) o_O?

Because one side is x² - x ² while the other is 2x...

Why not? :O

take x=2, it makes
2(2-2) = 0
and
(2+2)(2-2) =0
so 2(2-2)=(2+2)(2-2) ._.

Do it with a and b if you prefer

a²-a²=a(a-a) (a is factorized) = (a*a)-(a*a) (developed) = a²-a² so a²-a²=a(a-a)
a²-b²=(a+b)(a-b) (that's a rules, you can develop it to be sure of it)
so you have
a(a-a) = (a+a)(a-a) so X (X - X) = (X + X) (X - X)

I missed the first line but i got the second line right.

The first line :O..

X=X.. it's as if you were saying 10000=10000 (it's an useless line)

In addition, you just state that X=1.

The only way you can get 2X I think is by doing X*X, not X+X. Right?

Eh, X*X = X² and X+X = 2X
Take X=4
4*4 = 4²=16 and 4+4=8 which isn't 16

Nubs, come back when you play with three-dimensional vectors and integral calculation.

^This is what Docs have OF COURSE to know .

Oh.. Integrals and three-dimensional vectors .. Old days .. I just didn't think anyone would understand integrals on forums lul

Ok I was lost after:
X=1 and by definition, X = X .......

oww
I'll give you some maths lessons if you want

X=1 not 2 thats where the mistake is

This "demonstration" shows you why dividing by 0 is impossible : it would make incoherences such as 1=2
At the end, you get X=2X, and you stated that X=1 so basically, 1=2x1=2, which is impossible

[Zaonabiuibil]

<=> X(X - X) = (X + X)(X - X) (Factorize, Note that a²-a²=a(a-a), and that a²-b²=(a+b)(a-b))

You could show (X+X)(X-X), which gets X^2+X^2-X^2-X^2=0

And so X(X-X)=0, which you can check by first solving in the parenthesis, X-X=0. Then X(0)=0, so 0=0 which means that the incorrect portion is the X(X-X)=(X+)(X-X) in which it just ends there, there are no 1s or 2s.

the incorrect portion is the X(X-X)=((X+)(X-X) in which it just ends there, there are no 1s or 2s.

I don't understand what you mean :O

Oh you forgot an X

X(X-X)=((X+X)(X-X)

Well, It isn't incorrect o.O

take x=2, it makes
2(2-2) = 0
and
(2+2)(2-2) =0
so 2(2-2)=(2+2)(2-2)

You can write it, even if it isn't usual.. It is true

10000000*0 = 3402334302994029042*0 = 0*0 = 1*0 ._.

My bad on the X, was typing quickly.

And if you can say that, X doesn't equal 2, it equals all real numbers.

I see what I did wrong. (x+x) (x-x) is 2x timessss 0. My brain shut down and thought there was a + in the middle of the two. (x-x) gives 0 and 2x x 0 = 0.

I got lost after line1
