Which of the following tables shows the correct steps to transform x2 + 8x + 15 = 0 into the form (x − p)2 = q? [p and q are integers]

Step 1 x2 + 8x + 15 − 1 = 0 − 1
Step 2 x2 + 8x + 14 = −1
Step 3 (x + 4)2 = −1

Step 1 x2 + 8x + 15 − 2 = 0 − 2
Step 2 x2 + 8x + 13 = −2
Step 3 (x + 4)2 = −2

Step 1 x2 + 8x + 15 + 1 = 0 + 1
Step 2 x2 + 8x + 16 = 1
Step 3 (x + 4)2 = 1

Step 1 x2 + 8x + 15 + 2 = 0 + 2
Step 2 x2 + 8x + 17 = 2
Step 3 (x + 4)2 = 2
