Answer 2

Answer:

➝ 4x² + y² + z² - 4xy - 2yz + 4xz

➝ 2²x² + y² + z² - 4xy - 2yz + 4xz

➝ (2x)² + y² + z² - 4xy - 2yz + 4xz

➝ (2x)² + (y)² + (z)² - 2(2x) (y) + 2 (-y) (z) + 2 (2x) (z)

Using (a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ac

➝ [2x + (-y) + z]²

➝ [2x - y + z]²

➝ [2x - y + z] [2x - y + z]
