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] a. step 1 x2 + 6x + 8 − 1 = 0 − 1 step 2 x2 + 6x + 7 = −1 step 3 (x + 3)2 = −1 b. step 1 x2 + 6x + 8 + 1 = 0 + 1 step 2 x2 + 6x + 9 = 1 step 3 (x + 3)2 = 1 c. step 1 x2 + 6x + 8 − 2 = 0 − 2 step 2 x2 + 6x + 6 = −2 step 3 (x + 3)2 = −2 d. step 1 x2 + 6x + 8 + 2 = 0 + 2 step 2 x2 + 6x + 10 = 2 step 3 (x + 3)2 = 2
