Evaluate: (i) |(x^2+x y+y^2,x+y ),(x^2-x y+y^2,x-y)|

Find the linear factors of 2x^2-y^2-x+x y+2y-1.

Find he linear factors of 2x^2-y^2-x+x y+2y-1.

Find the linear factors of 2x^2-y^2-x+x y+2y-1.

Add : x^(2) y^(2) , 2x^(2)y^(2) , - 4x^(2)y^(2) , 6x^(2)y^(2)

If x^(2)+(x)/(y^(2))=y^(2)+(y)/(x^(2))=2 then find x^(2)+y^(2)
