If I have a garden that is square with sides of length x feet and next spring I plan to make it rectangular by lengthening one side 3 feet and shortening the other side by 3 feet.
Find a polynomial A(x) that represents the new area.
By how much will the area of the new garden differ from that of the old garden?

Old garden : x by x or x^2
new garden :(x3) by (x+3)
A(x) = (x+3)(x3) or x^2  9
difference = old garden  new garden
= x^2  (x^2  9)
= 9
