Step-by-step explanation:
Since we have an x under that radical, we have to get it out from under there. To do that, do the opposite of the square root, which is to square. But because this is an equation, you have to do the same thing to both sides. Doing this gives you

Get everything on one side and set the quadratic equal to 0 and solve for x:

Factor this into 2 factors of (x - 3)(x - 3) = 0. As you can see they are both the same, so x - 3 = 0 and x = 3. That's your answer. x = 3.
