To complete the square: 1) Move constant term: \(x^2 + 6x = 7\). 2) Take half of coefficient of x \((6/2 = 3)\) and square it \((3^2 = 9)\). 3) Add this to both sides: \(x^2 + 6x + 9 = 7 + 9\). 4) Factor left side: \((x + 3)^2 = 16\). 5) Take square root: \(x + 3 = \pm4\). 6) Solve: \(x = -3 + 4 = 1\) or \(x = -3 - 4 = -7\).
