Answer 2

The new polynomial identity is 2(x² + 2xy + y²)

Given,

The polynomial identities

Column A    Column B

(x − y)             (x2 + 2xy + y2)

(x + y)             (x2 − 2xy + y2)

(y + x)             (ax + b)

(y − x)             (cy + d)

We have to square an identity from column A and add it with any one identity from column B.

So,

Lets take (x + y)      

(x + y)² = x² + 2xy + y²

We can add this identity with x² + 2xy + y² in column B.

That is,

x² + 2xy + y² + x² + 2xy + y²

= 2x² + 4xy +2 y²

= 2(x² + 2xy + y²)

That is,

The new polynomial identity is 2(x² + 2xy + y²)
