Question

Factorise 30xy-12xy-12xy+10y-y

Answer 1

EQUATION GIVEN:-

=30xy-12x+10y-4 ----------------(1)

It could be written as:-

=2 (15xy-6x+5y-2) --------------(2)

Further taking only,

=15xy-6x+5y-2 -----------------(3)

Factorising this we get,

=5y (3x+1) -2 (3x+1) --------------(4)

Here we take 3x+1 common and the remaining we join and form one expression...and so we get=

(5y-2) (3x+1)

But this must be equal to 2 (5y-2) (3x+1)

as in second case 2 was taken out....so we now multiply 2 here...

Hope this helps!
