Question

Find the product of the following using the identity : (a + b) power 2 = a power 2 + 2 ab + b power 2. c) ( 2 pq + 1) power 2. d) ( 1 /2x + x) power 2.​

Answer 1

This is your answer take it .

Answer 2

Answer:

Step-by-step explanation:

(a+b)² = a²+2ab+b²

(2pq+1)² = (2pq)² + 2x2pqx1 + 1²

            = 4p²q² + 4pq + 1

            = 4pq ( pq+1+1)

            = 4pq ( pq+2)

( 1 /2X + X)² = (1/2X)² + 2×1/2X×X + X²

                  = 1/4X² +X²+ X²

                  =  1/4X² + 2X²

                  = 9X²/4
