Problema Solution
The area of a rectangular field is given by the trinomial t^2-4t-45. The length of the rectangle is t-5. What is the expression for the width of the field?
Answer provided by our tutors
Area = t^2-4t-45
Length = t-5
Width = ?
Area = Length*Width
Width = Area/Length
Width = (t^2-4t-45)/(t - 5)
Width = (t - 9)(t + 5)/(t - 5)
