Answer 1

Step-by-step explanation:

8)Given expression is apq+bcpq-ar-bcr

=>pq (a+bc)-r(a+bc)

=>(a+bc)(pq-r)

apq+bcpq-ar-bcr=(a+bc)(pq-r)

10) Given expression is

4(x+y)(3a-b)+6(x+y)(2b-3a)

=>2(x+y)[2(3a-b)+3(2b-3a)]

=>2(x+y)(6a-2b+6b-9a)

=>2(x+y)(4b-3a)

4(x+y)(3a-b)+6(x+y)(2b-3a)=2(x+y)(4b-3a)
