Answer:

#3v^2(v^4-3v^2+49)#

Explanation:

That's as far as I was able to get with it. The quadratic formula reveals no real solution for v.
Unless you're looking for imaginary and real solutions, I think that's about all you can do with it.
If it was able to be factored you would end up with something that looks like #3v^2(v^2+?)(v^2-?)#.
