Question

What will be the answer of this question?​

Answer 1

Answer:

7x ² + 2xy + 7y²

Step-by-step explanation:

(2x² - xy + 5y²) - ? = ( - 5x² - 3xy - 2y²)

⇒ (2x² - xy + 5y²) -  ( - 5x² - 3xy - 2y²) = ?

⇒ 2x² - xy + 5y² + 5x² + 3 xy + 2y² = ?

⇒ 7x ² + 2xy + 7y² = ?

(7x ² + 2xy + 7y²) should be subtracted

Answer 2

Answer:

-3x^2-2xy+7y^2

Step-by-step explanation:

 2x^2-xy+5y^2

+(-5x)^2-3xy-2y^2

=-3x^2-2xy+7y^2
