We are doing solving polynomials using the zero factor property and here is the question:
Marie has a rectangular board 18 inches by 23 inches around which she wants to put a uniform border of shells. If she has enough shells for a border whose area is 282 square inches, determine the width of the border. (the border has x's as the width and length)

So the board AND the border have an area of
A2=(18+x)(23+x)
The board alone is
A1=18*23
A2A1=282
Solve for x.
