Question

Which of the following tables shows the correct steps to transform x^2 + 4x + 3 = 0 into the form (x - p)^2 = q?
[p and q are integers]
Step 1 x^2 + 4x + 3 + 1 = 0 + 1
Step 2 x^2 + 4x + 4 = 1
Step 3 (x + 2)^2 = 1


Step 1 x^2 + 4x + 3 - 1 = 0 - 1
Step 2 x^2 + 4x + 2 = -1
Step 3 (x + 2)^2 = -1

Step 1 x^2 + 4x + 3 - 2 = 0 - 2
Step 2 x^2 + 4x + 1 = -2
Step 3 (x + 2)^2 = -2

Step 1 x^2 + 4x + 3 + 2 = 0 + 2
Step 2 x^2 + 4x + 5 = 2
Step 3 (x + 2)^2 = 2
