About this MCQ
Medium SAT item. Correct choice: C. x = -8 or x = 4.
- A. x = -8 or x = 5
Why not A: “x = -8 or x = 5” is not x = -8 or x = 4.
- B. x = -7 or x = 3
Why not B: “x = -7 or x = 3” is not x = -8 or x = 4.
- C. x = -8 or x = 4 ✓
- D. x = 8 or x = -4
Why not D: “x = 8 or x = -4” is not x = -8 or x = 4.
Correct answer
C. x = -8 or x = 4
Explanation
x = -8 or x = 4 (option C) is the accepted answer to “Solve for x: x² + 4x - 32 = 0”. Option A (x = -8 or x = 5) is a different value from x = -8 or x = 4. Option B (x = -7 or x = 3) is a different value from x = -8 or x = 4. Option D (x = 8 or x = -4) is a different value from x = -8 or x = 4. Keep x = -8 or x = 4 as the SAT fact for this stem.
