- A square rug has an area of 49x^2-56x+16.

- A second square rug has an area of 16x^(2 )+24x+9.

What is an expression that represents the difference of the areas of the rugs?

Select two different ways to identify the solution. Do the two methods give you the same result? Justify.

(49x^2 - 56x + 16) - (16x^2 + 24x + 9)

49x^2 - 56x + 16 - 16x^2 - 24x - 9

33x^2 - 80x + 7

You could simply subtract the numbers as is, which I've shown above. Or, you may be able to factor first, then subtract.

Hope this helps!! :)
