i have a problem...
is there a way to copy and paste images onto here? because I found a math problem that I can't figure out!
you can attach an image by clicking the "Attach File" button below.
save your image locally as a .png file and then just attach it.
k, I'll have it up in a minute :)
what did they do wrong? I can't figure it out!
you cannot divide by zero
so dividing both sides by (x-x) is not a valid operation in mathematics
think of 10/x and lets say x starts off as being equal to 10 and then slowly reduce its value down towards zero. what happens to the value of 10/x?
it's divided by zero... but even though (x-x)=0, it's not exactly dividing by zero... I thought :P
it IS dividing b zero. otherwise you could prove any relation, e.g.:\[6*0=19*0\]\[\therefore 6=19\]
mmm... I guess I see. Man, I was hoping I had found an unsolvable math problem! I guess I'll have to keep looking :)
:-) good luck on your quest!
