Question

give me the answer of
(-a-b)^2

Answer 1

Solution :

( - a - b )²

= [ - ( a + b ) ] ²

= ( a + b )²

= a² + 2ab + b²

Hence,

( - a - b )² = a² + 2ab + b²

Answer 2

Hey Mate ✌

Here's your answer friend,

*************************************************

==> (-a - b)² = (-a)² - 2(-a)(b) + (b)²

...............{ by using the identity (a - b)² = a² - 2ab + b² }

==> (-a - b)² = a² + 2ab + b²

Is the required answer.

HOPE IT HELPS YOU :)
