Answer 1

Answer:

$hello$

L.H.S = (4pq + 3q)2 − (4pq − 3q)2 = (4pq)2 + 2(4pq)(3q) + (3q)2 − [(4pq)2 − 2(4pq) (3q) + (3q)2] = 16p2q2 + 24pq2 + 9q2 − [16p2q2 − 24pq2 + 9q2] = 16p2q2 + 24pq2 + 9q2 −16p2q2 + 24pq2 − 9q2 = 48pq2 = R.H.S (iii) L.H.S = (a − b) (a + b) + (b − c) (b + c) + (c − a) (c + a) = (a2 − b2) + (b2 − c2) + (c2 − a2) = 0 = R.H.S.

Answer 2

L.H.S = (4pq + 3q)2 − (4pq − 3q)2 = (4pq)2 + 2(4pq)(3q) + (3q)2 − [(4pq)2 − 2(4pq) (3q) + (3q)2] = 16p2q2 + 24pq2 + 9q2 − [16p2q2 − 24pq2 + 9q2] = 16p2q2 + 24pq2 + 9q2 −16p2q2 + 24pq2 − 9q2 = 48pq2 = R.H.S (iii) L.H.S = (a − b) (a + b) + (b − c) (b + c) + (c − a) (c + a) = (a2 − b2) + (b2 − c2) + (c2 − a2) = 0 = R.H.S.
