Question

verify that (11pq+4q)² = 176pq²​

Answer 1

Answer:

hey mate..

first of all take out L.H.S AND R.H.S.

L.H.S.

(11pq + 4q)² – (11pq – 4q)²  = (11pq + 4q + 11pq – 4q) × (11pq + 4q – 11pq + 4q)

[using a² – b² = (a – b) (a + b),]

here a = 11pq + 4q and

b = 11 pq – 4q] 

= (22pq) (8q) 

= 176 pq² 

R.H.S.

176pq²

Hence Verified
