Question

8: What should be added to a2 + 2ab + b2 to obtain 4ab + b2 ?​

Answer 1

Answer:

(2ab - a2)

Step-by-step explanation:

So, When we add this to the given problem..

We get..

=> a2 + 2ab + b2 + ( 2ab - a2 )

=> a2 + 2ab + b2 + 2ab - a2

=> 4ab + b2 [ a2 - a2 = 0 ]

So.. a2 gets cancelled off.. and thus you can get the required polynomial
