Try prove i'm wrong
>pro tip: you can't

you divide by zero in step 4

You divided by zero dipshit

to make it understandable for you idiots
a-b=0
(a+b)*(a-b)=b*(a-b)
(a+b)*0=b*0
0=0

Op is right

a = b
to get from line 4 to line 5 you divided by (a -b) when (a - b) is 0.

(a+b)(a-b) is not equal to b(a-b)
(a+b)(a-b) = a^2 - b^2
b(a-b) = ba - b^2

1!!! (Factorial) = 1

(a+b)(a-b) = 0
(a+b) = 2a
(a-b) = 0
(2a)(0) = 0

And then we have
b(a-b)
Or b(0)

2a(0) =/= b(0)

They both equal zero, but in the question it simply takes away 0 from both sides to get a+b = b

But the 0 is a multiplying factor, so to get rid of it you've gotta divide both sides by zero

Soo

2a(0) = b(0)

Get rid of the zero by dividing by zero on both sides

2a/0 = b/0

So

0=0

(a+b)(a-b) = b(a-b)
since a = b, a - b = 0
(a+b) * 0 = b * 0 which is true

Omg you fools you,ve doomed us all!

> 0=0

thats not the conclusion the OP comes to, you child.

If 1=a
and a=b

a = b
a^2 = a*b
a^2 - b^2 = ab - b^2
( a + b )*( a - b) = b ( a - b )
( a + b ) = b
a + a = a
2a = a
2 = 1

1=1
1^1 = 1*1
1^2 - 1^2 = 1*1-1^2
(1+1)(1-1)=1(1-1)
(1+1)=1
1+1=2
2(1)=1
2=1
Yeh he is right

You no need divide...

that because:
Is right!

won't work

if you times any number by 0 it gives you 0

dividing 0 by 0 is infinity

therefore you don't get the 5th step at all

(a-b) = 0.
Dividing both sides by (a-b) means you're dividing by zero.

>(1+1)=1
This is the only step I don't understand, someone explain

They're dividing both sides by (1-1), aka 0

you cant divide by zero you shit head, even if youre dividing 0 by zero

Dividing 0 by 0 does not equal infinity. It doesn't equal anything at all.

Sure you can divide 0 by 0 but the you get this
0/0 = x
0 = 0x
x=?

If a = b (which is our premise) then step 5 is not implied by step 4, since it involves dividing by (a-b) = (a - a) = 0. Therefore the conclusion is based on false premises and hence is invalid.

facepalm so hard

ok technically it gives you a non-existent value

so OP fucked up anyway

you can divide any number by 0, it gives infinity. just not 0 by 0

so you tellin me from a=b
your a+b=b?
