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

Statement 1: If e^(xy)+ln(xy)+cos(xy)+5=0, then (dy)/(dx)=-y/x . Statement 2: d/(dx)(xy)=0,y is a function of x implies(dy)/(dx)=-y/x .

Statement 1: If e^(xy)+ln(xy)+cos(xy)+5=0, then (dy)/(dx)=-y/x . Statement 2: d/(dx)(xy)=0,y is a function of x implies(dy)/(dx)=-y/x .

If 9+2(3x-xy+x^(2))+y^(2)=0 ,then what is the value of (3x^(2)-2xy+5y^(2)) ?

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

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

xy^(2)-x^(2)y-5=0

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