Answer:
Question :-
➪ (2x - y + 3z)²
Solution :-
➪ (2x - y + 3z)²
➭ (2x - y + 3z) (2x - y + 3z)
➭ 2x(2x - y + 3z) - y(2x - y + 3z) + 3z(2x - y + 3z)
➭ 4x² - 2xy + 6xz - 2xy + y² - 3yz + 6xz - 3yz + 9z²
➭ 4x² + y² + 9z² - 2xy - 2xy + 6xz + 6xz - 3yz - 3yz
➭ 4x² + y² + 9z² - 4xy + 12xz - 6yz
∴ The value of (2x - y + 3z)² is 4x² + y² + 9z² - 4xy + 12xz - 6yz
