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.
:
If you divide one side into the area of a rectangle, you can find the other side
so we can write it like this
s = %28%283x%5E2-2x-1%29%29%2F%28%283x%2B1%29%29
:
The numerator will factor
s = %28%283x%2B1%29%28x-1%29%29%2F%28%283x%2B1%29%29
:
note that we have (3x+1) in the numerator and the denominator, so we can cancel. leaving us with:
s = (x-1) ft is the other side

Did this reduce the confusion factor for you?
