WebSquare roots work on factors, not terms. So, you also can't take the square root of (x-1)^2-9 since it has 2 terms. By moving the 9 to the opposite side, and then taking the square root of both sides, you have individual terms on each side that you can apply the square root and be able to simplify them into: x-1 = +/-3. Hope this helps. Say we have a simple expression like x2 + bx. Having xtwice in the same expression can make life hard. What can we do?
