Enter a,b,c. Two real roots come out.
Uh? what ?!... I already played with Quadratic explorer, I don't see SOLVE here !
I have : Eq, Graph, Incr1, Lev4, Test. nothing more
Symb and Num keys are inoperative, is it buggy ? hidden ?
I tried many key on that screen, also with toolbox as you said, I don't understand...

Yes... not really straitforward.

ok proot works
But I'm new to this keyboard, it's so long to type proot... hey! I counted 11 keystrokes just to type proot([

Interresting there are many ways to get the result.
But I would like only one that could be straitforward...
...maybe the solve from quadratic explorer is the one.

please explain how you reach that solve function.
