Question

5. What must be subtracted from 2x square - xy - 5y square to make it -5x square– 3xy – 2y square?​

Answer 1

Answer:

(2x^7+x^6y-4x^4y^3-x^4-2x^3y^4-7x^3y-11x^2y^2+2xy^6-5xy^3+y^7)/((x-y)^3*(x^4+2x^3y+3x^2y^2+2xy^3+y^4))

Step-by-step explanation:

i think that will be it i dont know yet

Answer 2

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

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

then

x^2+3xy+y^2-2x^2+xy=-x^2+2xy+y^2 Ans.

hope it helps you
