The equation you provided in the image can be interpreted as follows:

We are given three integers $a$, $b$, and $c$ (where $a, b, c \in \mathbb{Z}$), and the equation:

$a^2 + b^2 + c^2 - 2ab = 6$

The goal is to find the value of $abc$.

Let's solve this equation step by step. The given equation can be factored as follows:

$a^2 + b^2 - 2ab + c^2 = 6$

This can be rewritten as:

$(a - b)^2 + c^2 = 6$

Now, we are tasked with finding integer values of $a$, $b$, and $c$ that satisfy this equation.

Approach:

We need to find integer values for $a$, $b$, and $c$ such that the sum of the squares $(a - b)^2 + c^2 = 6$. Let's consider possible integer values for $(a - b)$ and $c$ that satisfy this equation.
