Answer 1

Answer:

pls mark me as brainlist

Step-by-step explanation:

Correct option is

A

True

(2p−3q)2=4p2+9q2−12pq

L.H.S=(2p−3q)2

               =(2p−3q)(2p−3q)

               =2p(2p−3q)−3q(2p−3q)

               =4p2−6pq−6pq+9q2 

               =4p2+9q2−12pq

               =R.H.S

∴   (2p−3q)2=4p2+9q2−12pq
