How do I calculate velocity of an object if I know its Lorentz factor?

The question I have for my physics homework is "What does the velocity of an object need to be if it's Lorentz factor is 2?"
I know the equation for the Lorentz factor is γ = 1/sq(1-(v^2/c^2)) I just don't know how to get the velocity out of it.
I'm a bit of a math and physics noob so that might bit a slight problem aswell! :P Any help is appreciated!

You need to rearrange the equation, you know γ is 2 and c is the speed of light which is constant so you can find v which is the velocity of the object.

It is pretty simple algebra, have you attempted to try? Possibly show some work and we can be of more help.
