Quadratic Formula

Given integer coefficients

a b c

of a quadratic equation

 ax^2 + bx + c = 0

output the corresponding root(s) in exact simplified form

 [n1[/d1]] [±] [[i][√]n2[/d2]]

where each bracketed element must be omitted if possible.

If n1 is 0 but n2 is not, remove the space after the ± like so:

1 0 -5 => ±√5

If the solution comes to 0/0, output

indeterminate

If the solution comes to x/0, where x≠0, output

undefined
