Q. Solve the following algebraic expression: a² - b² - ( a + b )²
Solution:
a² - b² - ( a + b )²
Using identity ( a + b )² = a² + 2ab + b²
= a² - b² - [ a² + 2ab + b² ]
= a² - b² - a² - 2ab - b²
= - 2ab - b²
= - b ( 2a + b )
Answer: The correct and final answer of algebraic expression a² - b² - ( a + b )² is [ - b ( 2a + b ).
