st: Finding the roots (zeros) of an equation with stata

[Nathan Danneman <ndanneman@gmail.com>]

Hi all,

I would like to find the roots of complex univariate expressions, such
as y=x^3+2x^2-5.
By roots, I mean zeros.  As in the "root" of 2x+4 is -2 (the place
where the graph of the line crosses the x-axis).

Are there commands for this?

Thanks,
N
