Question

verify the following =
solve it​

Answer 1

Answer:

Step-by-step explanation:

(11pq +4q)^2 -(11pq - 4q)^2 =176pq^2

RHS:

using (a^2 - b^2) = (a + b)(a - b)

(11pq +4q +11pq -4q)(11pq +4q -11pq +4q)

(22pq )(8q)

176pg^2

=LHS

hence proved

Answer 2

Hope it helps!

Just get thorough with the identities, it helps a lot.

Solve step by step so there is less chance of making mistakes :)
