The answer is 0. Why?

a2x is the just: a * 2 * x (a multiplied by 2 and x). Thus, you can arrange a2x as '2ax' or 'ax2' and it would still mean the same thing. Looking at the equation "a2x - ax2". You can rearrange the "a2x" to "ax2". What is the "ax2 - ax2"? 

 

Another thing to keep in mind:

If a = 2, x= 3

Replace those numbers into the equation: a2x - ax2. It check out.

(2*2*3) - (2*3*2)

12 - 12 = 0

 

If you're still confused, ask.

If the question is how to factor this:     a2x - ax2     ,

 

    a2x - ax2                 factor out an  a  and an  x  from both terms.

 

=  ax(a - x)
