Question
If (a + b + c) = 9, find (a – 4)² + (b – 2) ² + (
c – 3) ² - 3(a – 4 ) (b – 2 ) (c – 3).Solution
a + b + c = 9 a + b + c = 4 + 2 + 3 (a – 4 ) + (b – 2) + (c – 3) = 0 If x + y + z = 0 x² + y² + z² = 3abc (a – 4)² + (b – 2) ² + ( c – 3) ² = 3(a – 4 ) (b – 2 ) (c – 3) (a – 4)² + (b – 2) ² + ( c – 3) ² - 3(a – 4 ) (b – 2 ) (c – 3) = 0
