Add 5x² + 2xy + 2y² & 2y² + xy + 4x²​

Answer 1

Step-by-step explanation:

Solution:-

$5x² + 2xy + 2 {y}^{2} + 2 {y}^{2} + xy + 4 {x}^{2} \\ = 9 {x}^{2} + 3xy + 4 {y}^{2}$

Answer 2

5x² + 2xy + 2y² & 2y² + xy + 4x²

(5x² + 2xy + 2y²) + (2y² + xy + 4x²)

5x² + 2xy + 2y² + 2y² + xy + 4x²

5x² + 4x² + 2y² + 2y² + xy + 2xy

9x² + 4y² + 3xy
