If `x,y in R` satisfy the equation `x^2 + y^2 - 4x-2y + 5 = 0,` then the value of the expression `[(sqrtx-sqrty)^2+4sqrt(xy)]/((x+sqrt(xy))` is

If x ,y in R satify the equation x^2+y^2-4x-2y+5=0, then the value of the expression [(sqrt(x)-sqrt(y))^2+4sqrt(x y)]//(x+sqrt(x y)) is sqrt(2)+1 b. (sqrt(2)+1)/2 c. (sqrt(2)-1)/2 d. (sqrt(2)+1)/(sqrt(2))

If x ,y in R satify the equation x^2+y^2-4x-2y+5=0, then the value of the expression [(sqrt(x)-sqrt(y))^2+4sqrt(x y)]//(x+sqrt(x y)) is a. sqrt(2)+1 b. (sqrt(2)+1)/2 c. (sqrt(2)-1)/2 d. (sqrt(2)+1)/(sqrt(2))

If x ,y in R satify the equation x^2+y^2-4x-2y+5=0, then the value of the expression [(sqrt(x)-sqrt(y))^2+4sqrt(x y)]//(x+sqrt(x y)) is a. sqrt(2)+1 b. (sqrt(2)+1)/2 c. (sqrt(2)-1)/2 d. (sqrt(2)+1)/(sqrt(2))

If x,y in R satify the equation x^(2)+y^(2)-4x-2y+5=0, then the value of the expression [(sqrt(x)-sqrt(y))^(2)+sqrt(xy)]/(x+4sqrt(xy)) is sqrt(2)+1 b.(sqrt(2)+1)/(2) c.(sqrt(2)-1)/(2) d.(sqrt(2)+1)/(sqrt(2))

If 5x^(2) + 4xy + y^(2) + 2x + 1= 0 then find the value of x, y

If 5x^(2) -4xy +y^(2) -2x +1=0 then value of x+y is

If x,y in R and satisfy the equation xy(x^(2)-y^(2))=x^(2)+y^(2) where xne0 then the minimum possible value of x^(2)+y^(2) is

If x,y in R and satisfy the equation xy(x^(2)-y^(2))=x^(2)+y^(2) where xne0 then the minimum possible value of x^(2)+y^(2) is

If x,y in R and satisfy the equation xy(x^(2)-y^(2))=x^(2)+y^(2) where xne0 then the minimum possible value of x^(2)+y^(2) is
