Finding roots of polynomial

[WedgeAntilles]

Hi there,

I am reading the hp prime user guide.

On page 55, there is an example to find the roots of 2x^2+3x-2.

I do as the manual says, proot(2*x^2+3*x-2) and the hp prime answers []

Inside the braclets there is no info about the 2 roots.

Note: the ^inside the proot(2*x^2+3*x-2) , I dont input it in the hp prime.

What am I doing wrong??

Many thanks,
