Question

find the product: 1) (pq-2r) (pq-2r)​

Answer 1

Answer:

pq×pqr×r

=p×q×p×q×r×r

=p^2×q^2×r^2

=p^2q^2r^2

Answer 2

Answer:

(pq)² - 4pqr + 4r²

Step-by-step explanation:

We can find the product by using the identity of ( a - b )²

i.e. (pq - 2r)²

Therefore, it will be

(pq)² - 2 x pq x 2r + (2r)²

= (pq)² - 4pqr + 4r²
