Show that.
(4pq + 3q)² - (4pq-3q)² = 48pq²
Please kindly solve it on a piece of paper

yes
4pq + 3q)² – (4pq – 3q)² = 48pq²
As we know,
(a + b)² = a² + b² + 2ab
and
(a – b)² = a² + b² – 2ab
So, we have to apply the above identities in the given equation.
(4pq + 3q)² – (4pq – 3q)² = L.H.S.
= (16p²q² + 9q² + 24pq²) – (16p²q² + 9q² – 24pq²)
= 16p²q² + 9q² + 24pq² – 16p²q² – 9q² + 24pq²
= 24pq² + 24pq²
= 48pq²
= R.H.S.
As we know,
(a + b)² = a² + b² + 2ab
and
(a – b)² = a² + b² – 2ab
So, we have to apply the above identities in the given equation.
(4pq + 3q)² – (4pq – 3q)² = L.H.S.
= (16p²q² + 9q² + 24pq²) – (16p²q² + 9q² – 24pq²)
= 16p²q² + 9q² + 24pq² – 16p²q² – 9q² + 24pq²
= 24pq² + 24pq²
= 48pq²
= R.H.S.
LoL you copied my ans.

thanks
soory I can't do because I am in 8th class
thanks
48q2 bcz (a+b)2 +(a-b)2 is a2 +b2+-2ab so answer is 48q2
:)
use identity a2-b2 so( 4pq+3q+4pq-3q) (4pq+3q-4pq+3q). after solving that 8pq*×6q=48pq2 = rhs
this is right identity
hi
(a+b)2=a2 +b2 +2ab +(a-b)2=a2 + b2 - 2ab use this formula
