The area of a rectangular swimming pool is given by 3x^2-2x-1ft^2 . One side length of the pool is given by 3x + 1 feet. What is an algebraic expression for the other side length of the pool? Simplify this, and include correct units as part of your answer.

The area = 3x^2-2x-1ft^2 .
One side length= 3x + 1 feet.
Area = L*W
Area / Length = Width

%28%28x-1%29%283x%2B1%29%29%2F%283x%2B1%29=width
%28%28x-1%29%28cross%283x%2B1%29%29%29%2F%28cross%283x%2B1%29%29=width
Width = (x-1)feet
