If x/y + y/x = -1 , ( x unequal y, y unequal 0) then the value of x^2 - y^2 is?
Maurinko [17]

Take your original equation \frac{x}{y} +\frac{y}{x} =-1

and multiply both sides by xy to remove the fractions. You are left with

x^2+y^2=-xy

So, x^2+y^2=-xy

Update: There is no numerical answer that can be found without being given a value for either x or y
