The given expression is:

$(6m - 6)^2$

This is a binomial square, which can be expanded using the formula:

$(a - b)^2 = a^2 - 2ab + b^2$

Here, $a = 6m$ and $b = 6$. Applying the formula:

$(6m - 6)^2 = (6m)^2 - 2(6m)(6) + (6)^2$

Now, let's simplify step by step:

$(6m)^2 = 36m^2$ $-2(6m)(6) = -72m$ $(6)^2 = 36$

Thus, the expanded form is:

$36m^2 - 72m + 36$
