Correct answer
C. x = 3 or x = -2
Explanation
x = 3 or x = -2 (option C) is the accepted answer to “Solve for x: x² - 1x - 6 = 0”. Option A (x = 3 or x = -1) is a different value from x = 3 or x = -2. Option B (x = -3 or x = 2) is a different value from x = 3 or x = -2. Option D (x = 4 or x = -3) is a different value from x = 3 or x = -2. Keep x = 3 or x = -2 as the SAT fact for this stem.
