### Missing close brace

hi!

Im getting "Missing close brace" when I try to prettyprint an expression on sage cloud.

the expression Im trying to prettyprint using show() is the result of using solve() on an equation system and saving it in the variable "a", I can see the contents of "a" but I can't prettyprint it.

thanks!

EDIT:

show (a[0]) works ~~great!~~great for showing the first element, but I still cant get the whole thing to show.

here is the code that produces the error

f=4*(x^3-x/4)^3+4*x-4*(x^3-x/4)
solve (f==0,x)
show (solve (f==0,x))

here is a pic
