Answer:
O (x - 2)
Explanation:
To find the expression that represents the length of one side of a rectangle, we need to factor the given expression 3x^2 - 5x - 2.
The factored form of the expression 3x^2 - 5x - 2 is:
(3x + 1)(x - 2)
From the factored form, we can see that the length of one side is represented by the expression (x - 2).
Therefore, the expression that represents the length of one side is
(x - 2).
