Correct answer
D. x = -7 or x = -5
Explanation
x = -7 or x = -5 (option D) is the accepted answer to “Solve for x: x² + 12x + 35 = 0”. Option A (x = 7 or x = 5) is a different value from x = -7 or x = -5. Option B (x = -6 or x = -6) is a different value from x = -7 or x = -5. Option C (x = -7 or x = -4) is a different value from x = -7 or x = -5. Keep x = -7 or x = -5 as the SAT fact for this stem.
