If `5x^2-4xy+y^2-2x+1=0` then `x+y=`

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

If 8x^2 + y^2 -12x -4xy+9 =0 , then the value of (14x-5y) is:

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

If x ^(2) + 5xy + y^(2) =-2x + y -6=0 then y'' at (1,1) is

Find the area of the triangle formed by the lines x^(2)-4xy+y^(2)=0 and x+y=1

If 8x^2+y^2- 12x - 4xy + 9= 0 , then the value of (14x - 5y) is: यदि 8x^2+y^2- 12x - 4xy + 9= 0 है, तो (14x - 5y) का मान ज्ञात करें |

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
