Question

8х^2 + xy – 4у²
3х^2 - 3xy +²y subtract the following​

Answer 1

=> 8x²-3x²+xy-3xy-4y²-y²

=> 4x²+7xy-3y²

answer => 4x²+7xy-3y²

Answer 2

Answer:

$5 {x}^{2} + 4xy - 5 {y}^{2}$

Step-by-step explanation:

$(8 {x}^{2} + xy - 4 {y}^{2} ) - (3 {x}^{2} - 3xy + {y}^{2} ) \\ 8 {x}^{2} + xy - 4 {y}^{2} - 3 {x}^{2} + 3xy - {y}^{2} \\ 5 {x}^{2} + 4xy - 5 {y}^{2}$
