You can put this solution on YOUR website!
Er...what would you like to do with this expression? Factor it maybe?
It would be most helpful if you were to provide some instructions with the problem you post.
Let's factor it, just in case that's what you wanted!
4x%5E2-9 Do you notice that this is a difference of squares?
%282x%29%5E2-%283%29%5E2 and this is factorable thus:
A%5E2-B%5E2+=+%28A-B%29%28A%2BB%29, so...
highlight%284x%5E2-9+=+%282x-3%29%282x%2B3%29%29
