Question

Add
8x² + 4xy - 6y²
4x² – 3xy+ 2y²
-4x² + xy - y²​

Answer 1

too hard but I can say that ² is square eg. 8² or 8² is 64

explanation: 8×8 is 64

I don't understand about x and y

so I couldn't solve he problem because of x and y

Answer 2

Step-by-step explanation:

Add like terms together

(8x² + 4x² - 4x²) + ( 4xy - 3xy + xy ) + ( -6y²+ 2y² -y²)

=》 8x² + 2xy - 5y² ANS
