let do it easy way......
let number required de x
then ,
(2x^2 - xy + 5y^2) - x = -5x^2-3xy-2y^2 ( solve in equally)
x= 2x^2 -xy + 5y^2 + 5x^2 - 3xy -2y^2
x= 7x^2 - 4xy + 3y^2
let number required de x
then ,
(2x^2 - xy + 5y^2) - x = -5x^2-3xy-2y^2 ( solve in equally)
x= 2x^2 -xy + 5y^2 + 5x^2 - 3xy -2y^2
x= 7x^2 - 4xy + 3y^2

answer is
this is how you applogise very good manners taught to you
-3x^2-4xy +3y^2
no 7x^2+2xy+7y^2
bro mene ye question rd sharma mae se dia hai aur Usme answer hai -3x^2-4xy+3y^2
some times books can also be wrong be it rd or ncert or rs
