Title: math challenge
Post by: particle on November 28, 2014, 09:57:44 AM
try not to google the answer!
wheres the error?
let a = b
a squared = ab
a squared + a squared = a squared + ab
2a squared = a squared + ab
2a squared - 2ab= a squared + ab - 2ab
2a squared - 2ab= a squared - ab
2(a squared - ab)= 1(a squared - ab)
2 = 1

sorry about the "squared" term, hard to do the little 2. so obviously 2 is not = 1 so wheres the error?

I know the answer but don't want to spoil it. So if you want to figure it out ignore this.

(a^2 -ab) = 0 so on your last term, you're dividing both terms by 0. Crazy things can happen when you do that.
