I am trying to write this proof for class. I am trying to prove by contradiction so I try to prove that 0 is greater than or equal to 1.
"Case 1" gives 1>0 which is a contradiction.
"Case 2" is 1=0, which I can't disprove. Anyone have a proof for that? I've tried a=1 and playing with the algebra (this seems like the right track, though I'm not sure), but I can't get anywhere from there.
I have a test tomorrow, so either a proof that 1 doesn't equal 0 or a big hint would be greatly appreciated.
