I need help simplifying radicals. The problem in priticular is the square root of 60x^2

Question

√60x^2 can be simplified this way:

√(4 * 15 * x^2)

Can you see what to take out from under the square root sign?

√4 = 2 and √x^2 = x

Therefore, we end up with this:

2x√15

And that's as far as you can go to simplify this one!

I hope this will help.
