Thanks for clarifying that. So I want to explain to my cousin why ##0x = 0## and ##x = 0/0## are not the same thing, in that x is undefined in the latter. How would you do it in a simple and concise manner?

So an equation can have more than one solution and formula cannot? What is the difference between a formula and equation?

Thanks, At least now when I explain this in person on Saturday (after collecting my money), I know this is the consensus view on the matter. Just so I know I have this down pat... If 3y=6 and y=6/3 are both satisfied by y=2 And 0y=1 and y=1/0 can't be satisfied in either, as there is no...

Is this still your view on y(x-1)=x2-1 as in should a hole be depicted? or are you now in the "y(x-1)=x2-1 and y=(x2-1)/(x-1) not being the same thing" camp?

I gave my cousin a call, because it seemed strange that he would offer me $20 with no down side. As it turns out, FactChecker was right and I'm getting that $20 (Thanks FactChecker) but yes he had an ulterior motive. He was using it to butter me up for some crank paper he's drafted called...

Hi Aufbauwerk, I can't make sense of your approach to the question.

This is how the question was posed: Yo Cuz, You want to make $20? Graph this equation [ y(x-1)=x^2-1] and then explain its unusual feature. If you do it correctly I'll give you $20. Look forward to seeing you and your graph at Tony's wedding next Saturday. Ciao So yea, I've got a very...

Hello Forum, I've gone about graphing the below equation by inserting values in for y and then solving for x: y(x-1)=x2-1 For instance, I say y=3 and then solve: 3(x-1)=x2-1 3x-3=x2-1 3x=x2-1+3 3x=x2+2 0=x2-3x+2 0=(x-1)(x-2) Thus x = 1 and 2 and so I plot co-ordinates (1,3)...
