<PRE><B>Question 384876</B>
The given solution is not correct.&lt;P&gt;
The following is the correct answer.&lt;P&gt;
{{{x^3 - a^3 = (x-a)(x^2 +ax + a^2)}}}&lt;P&gt;

In this example:  x is &#39;2x&#39;&lt;P&gt;
{{{(2x)^3 - 3^3}}}&lt;P&gt;

{{{(2x - 3)((2x)^2 + (2x)(3) + 3^2) }}}&lt;P&gt;

{{{(2x - 3)(4x^2 + 6x + 9 )}}}
