Question

What should be subtracted from x x square + X y + y square to obtain 2 X square + 3 x y

Answer 1

Step-by-step explanation:

Let, the answer be z.

Then, x² + y² - z² = 2x² + 3xy

-z² = 2x² + 3xy - x² - y²

z² = x² + y² -2x² - 3xy

z² = -x² + y² -3xy

z² = y² - x² -3 xy

z = √y²- x² - 3xy
