Question
(m + 2) 2 + (n - 1) 2 + (p +
6) 2 = 0, then find the value of 2m - 3n + p.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
