AFAIK, normally one would write:



If c is zero and b nonzero or b2=4 a c, then and only then there exists a unique solution of 0=a+bx+cx2.



Is it possible to interchange the if and the then clauses to emphasize the consequence? Is the following sentence good English?



Then and only then there exists a unique solution of 0=a+b x+c x2, if c is zero and b nonzero or b2=4 a c.



Looking at the answers to another question I have the impression that even the following should be more correct(?)



Then and only then exists there a unique solution of 0=a+b x+c x2, if c is zero and b nonzero or b2=4 a c.
