Let A = B.
Multply both sides by A.
Now its: A^2 = AB.
Subtrace both sides by B^2.
Now its: A^2 - B^2 = AB - B^2.
When you factor it, it becomes: (A + (A - = B (A - .
Simplify it, making it: A + B = B.
Now, since A = B, you can make it: B + B = B.
Now to simplify: 2B/B = B/B.
Anything divided by itself is one, so the final equation would be: 2 = 1.

I cannot find an error in this equation, so.. What the hell?

also, since, A = B, then A - B = 0, therefore instead of simplifying into A + B = B, it simplifies into 0 = 0
this is an example of X = R, which stand for "x is an element of all real numbers"
it means in the equation of A = B, no matter what numbers u plug in as A or B, it would always come out as 1 = 1, 2 = 2, etc...

i learned this in my algebra-II class.... yesterday....

I hate these kind of problems... but I know one of them too.
Just give me time to find it....

This thread reminded me how much i love math

if there siamese twins

OMG..im so screwed once school starts for me, i suck in math -.-

Keep in mind, weary freshmen, that this is pretty advanced stuff (or at least not freshmen material); factoring itself isn't taught until Grade 11 in Canada.

A=B

This is the error.

Your maths teacher probably trying to cheat money out of you all.

Yeah pretty much except it's not the same as when x= all reals (not R, fancy R). x= all reals (AR) is a domain of an equation which is only the case when all the denominators cannot be equal to 0, all the logs and sqr roots are already greater than or equal to 0 (that is, they don't contain an x variable). You'll learn about it more in algebra 2.

Yea P can = T.

Don't look at them as letters in the alphabet or it will confuse you. They are just variables.

Whether its A=B or /=\ or Cheeseburger=Hotdog. It doesn't matter what the variable is called, they just there as a placeholder really. The value that they are assigned is what matters, not the name.

For example. lets look at Cheeseburger=hotdog.

Obviously a cheeseburger isn't a hotdog, so how can they be equal? Since these are both variables, we will assign them a value.

Lets say we go to a fast food place and see that we can buy a cheeseburger for $2, and also, a hotdog costs $2.

Cheeseburger = $2
Hotdog=$2

Cheeseburger=hotdog
$2=$2

See... the variables name means nothing, it's the values they represent that are what matters.
