      Question

      (m + 2) 2 + (n - 1) 2 + (p +

      6) 2 = 0, then find the value of 2m - 3n + p.
      A -13 Correct Answer Incorrect Answer
      B -3 Correct Answer Incorrect Answer
      C 5 Correct Answer Incorrect Answer

      Solution

      If (m + 2) 2 + (n - 1) 2 + (p + 6) 2 = 0, then (m = -2), (n = 1), and (p = -6).

      So,
      - m + 2 = 0 → m = -2
      - n - 1 = 0 → n = 1
      - p + 6 = 0 → p = -6

      Therefore, required value:
      2(-2) - 3(1) + (-6) = -4 - 3 - 6 = -13
