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 + + 9z² - 4xy + 12xz - 6yz
