You’d have to be an idiot to believe this. The second-to-last row equals 0 on both sides, so where the hell does “2=1″ come from?
2(a-b) is worked out as 2 times (a minus b). a and b are the same value, so it works out at 2 times (0), equaling 0, not 2. and a plus b minus 2b is worked out as (a + b) – 2b. since a nd b are the same value, (a + b) can be sated as 2b, or 2a, doesn’t matter. so it will work out as 2b – 2b, which equals 0
and 0 = 0 last time i checked. am i right?
False. Just substitute in any number
If a=b, then (a-b)=0. Therefore, 2(a-b)=0 and a-b=0, so 0=0, not 2=1.
The last operation is not a viable operation.
You just randomly took out the -2b Nice try though!!
After the third to last line they simplify ‘a + b – 2b’ to ‘a – b’, That’s valid. They then divide each side by (a-b). That’s valid too. I’m sure there’s an error, but it’s some inexplicable algebra ‘rule’ and I can’t find it.
You can’t divide by zero. Which is what a minus b is. Therefore the last operation isn’t valid.
Kella .. if you divide by (a – b) in the second to last line you don’t get 1 on the right side. You get (a / (a – b)) – (b / (a – b)). This is because both a & b would get divided separately by the (a – b). So everyone is right that this is stupid.
a=b. a-b=0. (a-b) divided by (a-b) is dividing by 0, which is always unallowed.
(a-b)/(a-b) is not valid, it’s 0/0.
Yeah, a bunch of these people already said it, but in case anyone didn’t understand: if a=b, then a-b=0. This is fine, but in the 2nd to last line, we divide both sides by a-b, and since a-b=0 we’re dividing by zero, which isn’t allowed in math.
Why you should never judge someone based on appearance...
Mom tells daughter the cat is hurt (arthritis) and to be careful with it. This is the little girl's response...
