Ok so I just proved 1 = -1. Someone help me find my error.

I could certainly be wrong, but I think the only problem is in the final division.

I don't see a problem with:

(-1)(V-E)^(1/2) = (V-E)^(1/2)

To use some concrete numbers, I think we all agree that sqrt(4) = -2

Then,

sqrt(4) = -2
sqrt(4) = (-1)*(2)
sqrt(4) = (-1)*(sqrt(4))

I don't believe you can divide both sides of the equation by a root, because it could be either positive or negative.
