```Can you describe your complete problem ? Nothing seems to be wrong with the
syntax except square braces around your expression. Square braces f[...] are
used to define arguments to a function. Eg:

In:= Simplify[((x-a)/A)^2+((y-b)/B)^2-2*r*(x-a)*(y-b)/(A*B)]
Out= (a-x)^2/A^2-(2 r (a-x) (b-y))/(A B)+(b-y)^2/B^2

In:= ((x-a)/A)^2+((y-b)/B)^2-2*r*(x-a)*(y-b)/(A*B)
Out= (-a+x)^2/A^2-(2 r (-a+x) (-b+y))/(A B)+(-b+y)^2/B^2
