The equation has two possible solutions for $Z_2$:

1. $Z_2 = -950.99$
2. $Z_2 = 108.73$

Given the physical context, if there are any constraints on $Z_2$ (e.g., if it must be positive), the appropriate solution would likely be $Z_2 = 108.73$.

Let me know if you would like further clarification or a specific verification.

Here are some additional related questions:

1. How can we verify which solution for $Z_2$ is physically meaningful?
2. What is the significance of the other variables $T$, $A$, and $Z_1$ in this equation?
3. How can we re-arrange similar quadratic equations to find unknowns?
4. What methods can be used to solve equations when multiple solutions exist?
5. How do changes in $T$ and $A$ affect the value of $Z_2$?

Tip: Always cross-check your final answers for physical or logical constraints when dealing with real-world equations.
