x=y x^2=xy x^2-y^2=xy-y^2 (x+y)(x-y)=y(x-y) x+y=y y+y=y 2y=y 2=1 can you find out the mistake?
The problem is in the step where you divide by (x-y)
Since x=y x-y=0
When you divide by zero you have infinity. Infinity times any number is still infinity.
What this really proves is 2*infinity=infinity
whoa you guys seem like mathmagicians.
