Question

1Expand the following using identities:(i) (3x+4y)2 (ii) (2a-3b)2​

Answer 1

Step-by-step explanation:

1} 6x + 8y

2} 4a - 6b

hope that this will help you

Answer 2

Answer:

1) (2x + 4y)² = 4x² + 16y² + 2 × 2x × 4y

= 4x² + 16y² + 16xy

identity (x+y)²= x²+y²+2xy

2 ) ( 2a -3b)² = 4a² + 9b² - 12ab

identity (x-y)²= x²+y²-2xy

hope it help
