Question

4(p+q)(3a-b)+6(p+q)(2b-3a)

Answer 1

(4p+4q)(12a-4b)+(6p+6q)(12b-18a)
=(8pq)(8ab)(12pq)(-6ba)

Answer 2

( Solving bracket )

=4p+4q × 3a-b+6p+6q×2b-3a

( Taking like terms )

=(4p+6p)(4q+6q)(3a-3a)(-b+2b)

= 10p×10q×b

=100bpq

I'm not sure but this might be the answer...

I prefer you to recheck if you can...
