AAAaannndd the bot gets it wrong yet again!
what a load of rubbish!

-x^2 + 2xy - y^2 = -(x^2- - 2xy + y^2) = -(x-y)^2

We can start by factoring the quadratic expression into two binomials:
-x^2 + 2xy - y^2 = (-x+y)(x-y)

To write this expression as the opposite of the square of a binomial, we just need to take the square root of each factor, put a minus sign in front, and multiply them together:

-(√(-x+y))^2 * (√(x-y))^2

Simplifying this expression, we have:

-(i√(x-y))^2 * (√(x-y))^2

-(i^2)*(x-y)

-(x-y)

Therefore, the answer is - (x-y).
