Identify the algebraic identity: (x-y)² = x² - 2xy + y²

• x² - 2xy + y²

• x² + 2xy + y²

• 2xy - y²

• x² - y²

Identify the algebraic identity: (a+b)² = a² + 2ab + b²

• (a+b)² = a² + 2ab + b²

• (a+b)² = a² - 2ab + b²

• (a+b)² = a² + 2ab - b²

• (a+b)² = a² + b²

Identify the algebraic identity: (m-n)² = m² - 2mn + n²

• m² - mn + n²

• m² + 2mn + n²

• m² - 2mn + n²

• m² - 2mn - n²

Verify the algebraic identity: (x-2y)² = x² - 4xy + 4y²

• (x-2y)² = x² - 4xy + 8y³

• (x-2y)² = x² - 4xy + 2y³

• Yes, the algebraic identity is verified.

• No

Expand (2x-y)²

• (2x-y)² = 4x² - 4xy + y²

• (2x-y)² = 4x² + 4xy - y²

• (2x-y)² = 4x² - 4xy - y²

• (2x-y)² = 4x² + 4xy + y²
