Consider the following operators defined below

$x@y$: gives the positive difference of $x$ and $y.$

$x\$y$: gives the sum of squares of $x$ and $y.$

$x₤y$: gives the positive difference of the squares of $x$ and $y.$

$x\&y$:gives the product of $x$ and $y.$

Also, $x,y\:\in\:R\:\text{and}\:x\neq y$. The other standard algebraic operations are unchanged.

The expression $[(x₤y)\div(x@y)]^2-2(x₤y)$ will be equal to

  1. $x₤y$
  2. $x\$y$
  3. $(x₤y)(x@y)$
  4. Cannot be determined
