Complete each statement in the steps to solve x2 – 4x + 3 = 0 using the process of completing the square. isolate the constant by both sides of the equation. add to both sides of x2 – 4x = –3 to form a perfect square trinomial while keeping the equation balanced. write the trinomial x2 – 4x + 4 as squared. use the square root property of equality to get x – 2 = ± . isolate the variable to get solutions of 1 and 3.
