Hi,

I wonder if exist a way to obtain this on my 41's and, of course, DM41L, X.

Assume we resolve 9x2+0x-62 :

Hp 41 says : x1 = 2.62
x2 = - 2.62

That is correct, but I would prefering see : SQRT(62)/3
- SQRT(62)/3

I canot write the mathematical symbol of the sqrt, (V-). Well hense is exist a
to do this ?

Best.
This forum "understands" MathJax, so you certainly can write something like $$\frac{\sqrt{62}}3$$ and $$-\frac{\sqrt{62}}3$$

To see that result you'd need a machine that has an "exact" mode such as the HP48G or the Prime. The HP-41C and therefore the DM41 is a numerical-only machine.
√ is U+221A in the Arial, Consolas & Verdana fonts

WORD:
√ is U+221A in Insert, Symbol...;
√ is Insert... Object... Create... New Microsoft Equation;
√ is 221A, Alt+X shortcut key;

LaTex;

are some of the available options for √

BEST!
