Question

find the value of a if :
pqa = (3p+q)² - (3p-q)²

Answer 1

Step-by-step explanation:

p x q x a = (3p + q)² - (3p - q)²

{simplifying the above by (a + b)² - (a - b)² = 4ab}

p x q x a = 12pq

a = 12

Answer 2

Answer:

(9p^2-q^2)/pq

Step-by-step explanation:

We Know That,

(a+b)^2×(a-b)^2 = a^2-b^2

By Applying This Formula We Get That

pqa= (9p^2-q^2)

a= (9p^2-q^2)/pq (Answer)
