I run the example ComputationalMathematicsExample.mlx in Symbolic Math Toolbox.

In Section Substitution and Solving is comparing the numerical solution and symbolic,

but numerical solution in line 34 should be

doubleSol = roots([6 -2 0 0 3 0 0 -8]) instead of doubleSol = roots([-8 3 -2 6]) % double-precision

For someone new it can be misleading.

Don't have subject toolbox for confirmation but if you think you have found either a bug or a documentation error, report it via a Support Request that you can find link to at the "contact us" link at top of page (the telephone icon), or just email <support@mathworks.com>. Include sufficient information to reproduce the issue, your version info and what you think is the issue and, if have one, a proposed solution.
