If LHS is(2a + 3)2Then RHS would be⇒ (2a + 3)2= (2a)2 + 32 + 2 × 2a × 3= 4a2 + 9 + 12a= 4a2 + 12a + 9The error is 4a2 instead of 2a2 and 12a instead of 6aHence = (2a + 3)2 = 4a2 + 9 + 12a

Answer :

If LHS is

(2a + 3)²

Then RHS would be

⇒ (2a + 3)²

= (2a)² + 3² + 2 × 2a × 3

= 4a² + 9 + 12a

= 4a² + 12a + 9

The error is 4a² instead of 2a² and 12a instead of 6a

Hence = (2a + 3)² = 4a² + 9 + 12a
