(iv) one
if you can then please help

Answer 1

Given Equation is (4pq+ 3q)^2 - (4pq - 3q)^2

(i) (a + b)^2 = a^2 + b^2 + 2ab

(ii) (a - b)^2 = a^2 + b^2 - 2ab.

Now,

= > 16p^2q^2 + 9q^2 + 24pq^2 - (16p^2q^2 + 9q^2 - 24pq^2)

= > 16p^2q^2 + 9q^2 + 24pq^2 - 16p^2q^2 - 9q^2 + 24pq^2

= > 48pq^2.

Hope this helps!
