The area of a rectangular athletic field is represented by the expression 48x^4 + 32x^3 - 72x square meters. Write an algebraic expression to represent one possible set of dimensions (in the sense Òlength times widthÓ) of the athletic field. Include correct units with your solution.
I got 8x(6x^3 + 4x^ -9)
I'm still not sure how to include correct units. Please help!
