Well, if one is looking for symbolic solutions, I don't know what else
to do other than solving for x, y, z such that the partial derivatives
are zero (and verifying that solutions are extrema and not saddle
points).

For numerical unconstrained optimization, there is lbfgs. For numerical
constrained optimization, there is cobyla and augmented_lagrangian.
