Algebra-2

Here is the step-by-step graphical solution for the given problem:

Step 1: Define the variables

Let's assume that the number of hours it takes Carl to complete the task is  hours. Then, Ben takes  hours to complete the task, and Alex takes  hours to complete the task.

Step 2: Set up the equations

The sum  of the number of hours each worker takes is given by:

The product  of the number of hours each worker takes is given by:

We know from the problem statement that the product of their work hours is  more than the sum of their work hours. So our equation is:

Step 3: Expand the polynomial expressions

First, expand :
