comment How to reduce a quartic form to a quadratic form with equal roots
@halirutan sorry, I should have made that clear. It only needs to be positive when the variables have 0/1 values.

comment How to reduce a quartic form to a quadratic form with equal roots
@halirutan sorry that was a typo. It was meant to be (xy-zw-1)^2. The positivity is the main challenge of the question. I have cross posted the question on the maths stackexchange.
