# NC Math 1 MVP 7.3: Factor Fixin'

*Optima’s Quilts*only made square blocks for quilters and Optima spent her time making perfect squares. Customer service representatives were trained to ask for the length of the side of the block, , that was being ordered, and they would let the customer know the area of the block to be quilted using the formula . Optima found that many customers that came into the store were making designs that required a combination of squares and rectangles. So,

*Optima’s Quilts*decided to produce several new lines of rectangular quilt blocks. Each new line is described in terms of how the rectangular block has been modified from the original square block. For example, one line of quilt blocks consists of starting with a square block and extending one side length by 5 inches and the other side length by 2 inches to form a new rectangular block. The design department knows that the area of this new block can be represented by the expression: . The diagram that represents the area and dimensions of the new block is drawn like this

## Task 7.3 Question 1

Label each of the areas of the diagram in your printed copy of the MVP task and use them to find a different expression to represent the area of this new rectangular block two ways. The first way is: . What is a second expression for the area? Use the ^ key to enter an exponent when typing your expression and remember to write is as A(x)=____.

## In this portion of the task you will use the Geogebra Applet to draw each diagram.

*Optima’s Quilts*has introduced. Find two different algebraic expressions to represent each rectangle, and illustrate with a diagram why your representations are correct.
