Factorise : $4(a+b) - 6(a+b)^{2}$.
Given: $4(a+b) - 6(a+b)^{2}$.
To do: Factories the expression
Solution:
The common factor of both terms in expression is 2(a+b)
So $4(a+b) - 6(a+b)^{2}$
=$2(a+b) \times [2 - 3(a+b)] $
=$2(a+b) \times [2- 3a -3b]$
=$2(a+b) \times (2 - 3a - 3b)$
Therefore , the answer is $2(a+b) \times (2 - 3a - 3b)$
