If `(x + y)^2 = 2(x^2 + y^2)` and `(x – y + lamda)^2 = 4, lamda > 0`, then `lamda` is equal to

If (x+y)^(2)=2(x^(2)+y^(2))and(x-y+lamda)^(2)=4,lamdagt0, then lamda is equal to :

If (x+y)^(2)=2(x^(2)+y^(2))and(x-y+lamda)^(2)=4,lamdagt0, then lamda is equal to :

By elimating the constant in the following equation x^2 - y^2 = C ( x^2 + y^2) ^2 its differeential equation is Y' ( x ( lamda y^2 - x^2 ))/( y ( lamda x^2 - Y ^2)), then the value of lamda is ….
