Suppose you cut a small square from a square of fabric as shown in the diagram. write an expression for the remaining shaded area. factor the expression. type your answer below.

To solve this problem you must apply the proccedure show below:

 1. You have the area of the larger square shown in the figure above, is:

 A=x²

 2. Then, you have the area of the smaller square shown in the figure above, is:

 A=3²
 A=9

 3. Therefore, the expression for the remaining shaded area is:

 A=x²-9
 A=(x-3)(x+3)
