First of all, I apologize if this isn't the correct website to ask this question on.

I know how to program the basic formula, but is it possible to program the formula to not simplify the roots? (so as to avoid irrational numbers)

You could just do the 2 calculations seperatly as the quadratic formula is a fraction. My answer is in pseudocode.

Quadratic Formula

f and g are the top parts, e is the bottom part of the equation. a, b and c are the inputs.

 e <- 2*a
 f <- -b + sqrt(b^2-4*a*c)
 g <- -b - sqrt(b^2-4*a*c)

 Pretty Print Here

Once you have them like that you could print them out as shown in the line below. I am not exactly sure how to pretty print in ti-basic. But it would like something like the below.

disp f,"/",e
disp g,"/",e

All you have to figure out how to get it to print on one line for each disp. You could also use output.
