Correct answer
B. x = -6 or x = 0
Explanation
x = -6 or x = 0 (option B) is the accepted answer to “Solve for x: x² + 6x + 0 = 0”. Option A (x = 6 or x = 0) is a different value from x = -6 or x = 0. Option C (x = -6 or x = 1) is a different value from x = -6 or x = 0. Option D (x = -5 or x = -1) is a different value from x = -6 or x = 0. Keep x = -6 or x = 0 as the SAT fact for this stem.
