x = {4*(r-1) + sqrt(56 -32r +56r^2 -U(x)*(1+r^2))}/(1+r^2)
and
x = {4*(r-1) - sqrt(56 -32r +56r^2 -U(x)*(1+r^2))}/(1+r^2)

"where r is constance"? I knew Constance... "Connie" for short... so X = Connie.

this isn't even an equation. there's no way to find x unless you know U(x). or if you know what r is.
