$\huge{\mid{\boxed{\sf{\color{purple}{AnS}{\color{pink}{WeR}}}}}\mid}$

From the given equation :-

3a² - 8ab - 2b² , 3a² - 4ab + 6b²

First Equation :-

3a² - 8ab - 2b²

Second Equation :-

3a² - 4ab + 6b²

Subtracting second equation by first equation :-

→ 3a² - 8ab - 2b² - ( 3a² - 4ab + 6b² )

→ 3a² - 8ab - 2b² - 3a² + 4ab - 6b²

→ 3a² - 3a² - 8ab + 4ab - 2b² - 6b²

→ - 4ab - 8b²

Therefore, on subtracting the second expression from the second expression we get - 4ab - 8b².
