Question

what should be added to x2+xy+y2 to get 2x2 +2​

Answer 1

Step-by-step explanation:

Let A = x²+xy+y²

Let B = 2x²+3xy ,

Let m should be added to A to obtain B.

=> m = (2x²+3xy) - (x²+xy+y²)

= 2x²+3xy-x²-xy-y²

= 2x²-x²+3xy-xy-y²

= x²+2xy-y²

Answer 2

Answer:

Let A = x²+xy+y²

Let B = 2x²+3xy ,

Let m should be added to A to obtain B.

=> m = (2x²+3xy) - (x²+xy+y²)

= 2x²+3xy-x²-xy-y²

= 2x²-x²+3xy-xy-y²

= x²+2xy-y²
