Q2. Factorize 5ax-3ay-5bx+3by

Factorization methods —

Solution:

We see here that in the first two terms ‘a’ is common and in last two terms ‘b’ is common.

5ax-3ay-5bx+3by

 =a(5x-3y)-b(5x-3y)

Put [] brackets;

 =[a(5x-3y)-b(5x-3y)]

Here we see (5x-3y) as common factor — taking it out we get,

 =(5x-3y)[a-b]

So , we got;

 5ax-3ay-5bx+3by=(5x-3y)(a-b)

i-e (5x-3y) and (a-b) are the factors
