You can put this solution on YOUR website! 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.
large square - inner square
f(x) = x^2 - (x-3)^2
f(x) = x^2 - (x^2 - 6x + 9)
f(x) = x^2 - x^2 + 6x - 9
f(x) = 6x - 9
