    How come multiplying the two radicals (square root of x + 2) causes them to cancel out? wouldn't you multiply what is inside the radical, therefore giving you the square root of x^2 + 4x + 4?

    How would I solve the problem if the 3 was another radical??? how would you do this problem if there were 2 radicals?
