How do i do this? method as well..

8x^3 + 12x^2 - 2x - 3.  This is the product in the form ax^3 + bx^2 + cx + d.

Step-by-step explanation:

We are told that the first and smallest of three consecutive positive integers is (2x - 1).  

The proper representation of the next integer is (2x - 1) + 2, or (2x + 1).

The third integer is (2x + 1) + 2, or (2x + 3).

The product of these three numbers is (2x - 1)(2x + 1)(2x + 3).

We need to multiply out this product.  Start with (2x - 1)(2x + 1).  This is a "special product" easily found:  (2x)^2 - 1, or 4x^2 - 1.

Now we have only to multiply this (4x^2 -1) by (2x + 3).  Using the FOIL method, we obtain:

8x^3 + 12x^2 - 2x - 3.  This is the product in the form ax^3 + bx^2 + cx + d.
