Question

Add
-5pq -7pq , and 12pq ​

Answer 1

Answer:

-5pq-7pq+12pq

=-5pq+5pq

=0

Answer 2

Here we have to add -5pq -7pq , and 12pq

This can be mathematically expressed as

-5pq -7pq + 12pq ​ ​

We will first take out the common terms out of these numbers

-5pq -7pq + 12pq ​ ​= pq ( -5 -7 + 12)

                             = pq ( - 12 + 12)

                             = pq ( 0 )

                             = 0

Hence,  the value on adding these numbers comes out to be 0
