As far as I know, there isn't a solution because the ^2 is to the x, not the 4, and since you obviously don't know what x is (unless you do- then there is a solution), it just stays like that. I hope I helped!

It can be factored into (2x)(2x), if that is what you were asked to do. However, from the way you have it stated, I'm not sure what you are asking. In the future, please be more specific in stating your problem. Thanks.

I hope this helps.
