Answer:

\huge\bold\orange{Given :-}

➪ 27x³ - y³ - z³ - 9xyz

\huge\bold\green{Solution :-}

➪ 27x³ - y³ - z³ - 9xyz

➭ (3x)³ + (- y)³ + (- z)³ - 3 × (3x) × (- y) × (- z)

➭ (3x - y - z) {(3x)² + (- y)² + (- z)² - 3x × (- y) - (- y) × (- z) - (- z) × 3x

➭ (3x - y - z) (9x² + y² + z² + 3xy - yz + 3xz)

∴ The answer of this question is

(3x - y - z) (9x² + + + 3xy - yz + 3xz)

\huge\bold\purple{Formula\: used :-}
