Can the following MWE be reduced by creating a command that can accept a formula then print and evaluate it without the need to write it twice in two different forms for both evaluating and printing as shown below?

The first root is evaluated by $x_1 = toprint = SIpgfmathresultcm $

AFAIK there is no such function available but I may be wrong. You could write your own parser that locally redefines the macros that print stuff to macros that wraps stuff in the respective functions. In the code below, I do that for frac and sqrt. This works in this case, also because you were kind enough to explicitly spell out multiplications and even used * for them. Clearly, this "parser" is fragile, but if you really feel it is worthwhile you may add other functions like sin and so on.

The current version does not work with SI, also because I didn't understand where the units cm come from, but this could be changed.
