Problema Solution
The area of a rectangular swimming pool is given by 5x^2-31x-28ft^2. One side length of the pool is given by 5x + 4 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.
Answer provided by our tutors
other side = (5x^2 -31x -28)/(5x+4)
On factorizins, we will get:
5x^2 - 31x -28 = (5x+4)(x-7)
So, other side = (5x+4)(x-7)/(5x+4) = (x-7).
Answer : (x-7).
