#1**+1 **

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.
