Answer 1

Answer:

- 3 pq

Step-by-step explanation:

Since , ( A - B ) ^2 = A^2 + B^2 - 2 AB

i.e ( 3 / 4 pq - 1 ) ^2

= ( 3 / 4 pq ) ^2 + 1 - 2 ( 3 / 4 pq )

&

( A + B ) ^2 = A^2 + B^2 + 2 AB

i.e ( 3 / 4 pq + 1 ) ^2

= ( 3 / 4 pq ) ^2 + 1 + 2 ( 3 / 4 pq )

A/Q :-

( 3 / 4 pq - 1 ) ^2 - ( 3 / 4 pq + 1 ) ^2

= - ( 3 / 2 pq ) - ( 3 / 2 pq )

= - ( 3 pq )
