Question

Which of the following tables shows the correct steps to transform x2 + 6x + 8 = 0 into the form (x - p)2 = q?
[p and q are integers]


Step 1 x2 + 6x + 8 - 1 = 0 - 1
Step 2 x2 + 6x + 7 = -1
Step 3 (x + 3)2 = -1

Step 1 x2 + 6x + 8 + 1 = 0 + 1
Step 2 x2 + 6x + 9 = 1
Step 3 (x + 3)2 = 1

Step 1 x2 + 6x + 8 - 2 = 0 - 2
Step 2 x2 + 6x + 6 = -2
Step 3 (x + 3)2 = -2

Step 1 x2 + 6x + 8 + 2 = 0 + 2
Step 2 x2 + 6x + 10 = 2
Step 3 (x + 3)2 = 2
