You can put this solution on YOUR website!
First of all, both of your terms have an 8 and an x in common, so take those factors out using the distributive property.

8x%5E3-32x=8x%28x%5E2-4%29

Now you have the difference of two squares in the parentheses that you should be able to factor with your special case rule.
