Question

From the sum of x²-2xy+y² and x²+2xy+y² subtract x²-4xy+4y²​

Answer 1

Answer:

The aanswer is  x²+4xy-2y²

Step-by-step explanation:

At first we have to find the sum of x²-2xy+y² and x²+2xy+y²

∴ (x²-2xy+y²)+(x²+2xy+y²)

= x²-2xy+y²+x²+2xy+y²

= 2x²+2y²

Now we have to subtract x²-4xy+4y²​ from 2x²+2y²

∴ (2x²+2y²)-(x²-4xy+4y²)

=  2x²+2y²-x²+4xy-4y²

= x²+4xy-2y²
