Quadratic explorer app SOLVE function. TOOLBOX->APP->Quadratic Explorer->SOLVE. Also the other function in there DELTA might be of interest.

Enter a,b,c. Two real roots come out.

Better though, type your formula in the cas and solve for x...

PROOT command

I'm sure your casio wasn't spitting out exact results for 3rd, 4th, 5th, or 6th degree polynomial as an exact formula for a 6th degree polynomial would be quite the math news...

If that isn't what you are looking for, explain with an example what you mean by "solve" the polynomial.
