From a square piece of cardboard with width x inches, a square of width x-3 inches is removed from the center. Write the area of the remaining piece as a function of x.
---------------
Area of original piece = x^2
Area of piece removed = (x-3)^2
----------------
EQUATION:
Area of Remaining piece = original area - area removed
A of remaining piece = x^2 - (x-3)^2
