Question

How much less is x²- 2xy + 3y² than 2x² -3y² + xy​

Answer 1

Answer:

so we can write the above thing as 2x² - 3y² +xy - ( x² - 2xy + 3y²)

2x² - 3y² +xy - x² + 2xy - 3y²

=x²-6y²+3xy

hope its helpful..@.@

Answer 2

Answer:

$(2 {x}^{2} - 3 {y}^{2} + xy) - ( {x}^{2} - 2xy + 3 {y}^{2} ) \\ \\ = 2 {x}^{2} - 3 {y}^{2} + xy - {x}^{2} + 2xy - 3 {y}^{2} \\ \\ = 2 {x}^{2} - {x}^{2} - 3 {y}^{2} - 3 {y}^{2} + xy + 2xy \\ \\ = {x}^{2} - 6 {y}^{2} + 3xy$
