Answer:
subtract 2nd bracket from the 1st one
(10-4pqr+3q)-(9pqr-8q+6)
Be careful !! Don't subtract 1st from 2nd one.
Now multiply the outer negative sign with inner signs(of second bracket),all signs of values of second bracket will be reversed:
=(10-4pqr+3q)-9pq+8q-6
open the other bracket
=10-4pqr+3q-9pqr+8q-6
now arrange the similar terms:
=10-6-4pqr-9pqr+3q+8q
=4-13pqr+11q
Rearranging
omitting negative sign (in the start)
=-13pqr+11q+4
=13pqr-11q-4.
=-(13pqr+11q+4)
