Question

factorise -12-3(a-b) ²

Answer 1

Heya User ✌

Here's your answer friend,

_________________________________

==> -12 -3(a - b)²

==> -12 -3(a² - 2ab + b²)............{Using the identity (a - b)² = a² - 2ab + b²}

==> -12 - 3a² + 6ab - 3b²

==> 3( -4 + a² + 2ab - b²)

Is the required answer.

HOPE IT HELPS YOU :)
