Problema Solution
The area of a rectangular athletic field is represented by the expression 25y^2-4z^2 square meters. What is 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.

Solution: Factoring the said quadratic equation:
25y^2 - 4z^2 = (5y + 2z)(5y - 2z)
If A = LW, then:
L = 5y + 2z
W = 5y - 2z
or can be the other way around.
