To square a binomial difference we subtract twice the product of both terms from the square of each term. Let binomial difference = x-y square of this = $(x-y)^{2}$ = $x^{2}$ - 2xy+ $y^{2}$.

#### Work Step by Step

To square a binomial difference we subtract twice the product of both terms from the square of each term. Let binomial difference = x-y square of this = $(x-y)^{2}$ = $x^{2}$ - 2xy+ $y^{2}$. Explanation- $(x-y)^{2}$ = (x-y)(x-y) = $x^{2}$ - xy -xy + $y^{2}$ = $x^{2}$ - 2xy+ $y^{2}$.
