For example, x²+6x+9=(x+3)². However, even if an expression isn't a perfect square, we can turn it into one by adding a constant number. For example, x²+6x+5 isn't a perfect square, but if we add 4 we get (x+3)². This, in essence, is the method of *completing the square*. ifinance bankWebSquare 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.
