Question

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

Answer 1

x² + y² + 4xy + 4y

Step-by-step explanation:

First add polynomial (i) and (ii)

As given

(x² - 2xy + y²) + (x² + 2xy)

x² - 2xy + y² + x² + 2xy

2x² + y²

Now subtracting x² - 4xy - 4y from 2x² + y²

(2x² + y²) - (x² - 4xy - 4y)

2x² + y² - x² + 4xy + 4y

:- x² + y² + 4xy + 4y

Required answer.

Hope it helps
