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.

Answer:
x = 1 1/2
Step-by-step explanation:
- If x = 1 1/2, x2 = 1 1/2 x 2 = 3
- i.e. 4x = 4 x 1 1/2 = 6
- So, 3 - 6 = -3
- -3 + 3 = 0
