Question 601490
The area of a rectangular athletic field is represented by the expression -8y^9 - 32z^4 + 56x^2 square meters. Write an algebraic expression to represent one possible set of dimensions (in the sense “length times width”) of the athletic field. Include correct units with your solution.

The furthest I know is that a common factor is 8?
-------
You can use 8
--> 8*(y^9 - 4z^4 + 7x^2) sq meters
or 8 meters by y^9 - 4z^4 + 7x^2 meters
--------------
Another is 
0.1 meters by 80y^9 - 320z^4 + 560x^2 meters
