Area Expansion for Square Components

A facilities technician is calculating the area of a square storage unit with a side length of (y−3)(y - 3) feet. To find the area, the technician needs to expand the expression (y−3)2(y - 3)^2 into a three-term polynomial (a trinomial). Based on the training for squaring binomials with subtraction, what is the final expanded trinomial, and what specific calculation is used to determine its middle term?
