Try prove i'm wrong
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?
