To solve the given optimization problem using Gurobi, we first need to understand and translate the natural language description into a mathematical formulation. The objective function is to minimize:

\[8 \times (\text{hours worked by Bobby})^2 + 6 \times (\text{hours worked by Bobby}) \times (\text{hours worked by Paul}) + 6 \times (\text{hours worked by Paul})^2 + 3 \times (\text{hours worked by Paul}) \times (\text{hours worked by Hank}) + 1 \times (\text{hours worked by Bobby}) + 9 \times (\text{hours worked by Paul}) + 1 \times (\text{hours worked by Hank})\]

Subject to the constraints provided, which include linear and quadratic constraints on the variables representing hours worked by each individual.

Let's denote:
- \(B\) as the hours worked by Bobby,
- \(P\) as the hours worked by Paul,
- \(H\) as the hours worked by Hank.

Given constraints can be grouped into linear and quadratic inequalities. For simplicity, we'll directly translate these into Gurobi code, noting that some constraints might require additional handling due to their quadratic nature or specific conditions (e.g., integer requirements for variables).
