Question 489027: I really need help on this one please..I don't understand this at all....
Essay: Show all work. The area of a rectangular swimming pool is given by 3x^2+11x+6 ft^2 One side length of the pool is given by 3x + 2 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 by chessace(471)   (Show Source):
You can put this solution on YOUR website! Area = given side * unknown side,
so unknown side = Area / given side.
Substitute the x polynomials and then either (a) divide (as in long division) OR (b) factor the Area polynomial expecting one of the factors to happen to be 3x+2, allowing a cancelation. As requested, it's not a bad idea to keep units through the process.
