$\huge\colorbox{white}{ \colorbox{white}{\colorbox{white}{Answer}}}$

Given :-

• 11ab²c + 22 ab - 11abc

To Find :

• Factorise

Solution :

$\sf\huge\implies$11ab²c + 11ab + 11ab - 11bc

$\sf\huge\implies$ 11ab (bc + 1) + 11ab (1 - c)

$\sf\huge\implies$ 11ab [ bc + 1 + 1 -c ]

$\sf\huge\implies$ 11ab [bc- c + 2]

Hence , factor of 11ab [bc - c + 2]
